Welcome to the fascinating world of integer word problems! Don’t let the fancy name scare you off; these problems might be easier and more fun than you think. Simplifying them is handy in daily life, and they’ll reappear in various forms throughout your academic journey. Let’s dive into the fundamental components.
In essence, integer word problems are mathematical problems involving number-related questions in the form of a story or practical situation. Specifically, these problems use integers — whole numbers that can be positive, negative, or zero. For instance, you might be asked how many more books Mike read than Sarah if Mike reads 15 and Sarah reads 7. Since you’re subtracting 7 from 15, you’re dealing with an integer word problem.
Mastering integer word problems plays a significant role in building your mathematical expertise. They help improve your problem-solving skills and enhance your ability to think logically and critically. Moreover, these problems are a cornerstone of real-world situations. Whether you are calculating the distance between two cities, determining profit and loss in business, or even figuring out temperature changes, integers and their problems come into play.
Are you ready to tackle integer word problems? Here are a few steps:
In dealing with integer word problems, practice is critical. The more problems you tackle, the more proficient you become. Happy problem-solving!
As a student or math enthusiast, knowing and mastering the basic concepts of integers will help you understand and tackle integer word problems better. In this section, we’ll delve into the definitions of integers, further distinguishing between positive and negative integers.
Integers are a number category that includes all the whole numbers, their opposites (negative counterparts), and zero. They are distinct from fractions, decimals, and percents. An integer can be a zero, a positive, or a negative whole number. The set of integers is denoted mathematically as {…, -3, -2, -1, 0, 1, 2, 3}. These numbers form the backbone of many mathematical operations and concepts, especially in algebra.
Positive and negative integers make understanding and calculating many real-world situations better and more efficient.
Positive integers , often natural numbers , are numbers greater than zero. They are frequently used to denote weight, distance, or money values. However, not all situations can be expressed with positive numbers; sometimes, we must resort to negative ones.
Negative integers are the opposites of natural numbers, excluding zero, and fall below zero on the number line. They are typically used when something is decreased, removed, or lost. An excellent example of using negative integers is in banking, where they represent debt. Or in meteorology, where they represent temperatures below zero.
Understanding the concept of positive and negative integers is paramount because they are central to successfully dealing with integer word problems. In the next segment, we will dive deeper into strategies for solving these problems, so tighten your seatbelts as we explore a fun section of the mathematical world.
When it comes to integers, understanding how to add and subtract these numbers is crucial, taking center stage in everyday mathematical operations. While learning, students begin grappling with word problems – mathematical problems presented in the form of a narrative or story – which include real-world scenarios. These serve as a bridge for children and adults to apply theoretical knowledge practically.
In terms of adding integers , there are a few rules to remember. If the integers have the same sign, add their absolute values and keep the standard sign. On the flip side, when the integers have different signs, subtract the smaller absolute value from the larger one and give the solution the sign of the number with the more considerable absolute value.
Subtracting integers , however, involves an additional step. More specifically, any subtraction can be reinterpreted as an addition. To subtract an integer, add its opposite. For example, to subtract -3 from 5 (5 – -3), we add 3 to 5 (5 + 3), with the sum coming to 8.
Let’s explore a few word problems that imitate daily life scenarios. Suppose a child has £5 and they want to buy a toy that costs £10. How many more pounds do they need? The problem here is 10 – 5, which equals 5. Thus, the child needs five more pounds.
In another situation, imagine the temperature was 5 degrees Celsius in the morning and dropped 3 degrees by the afternoon. What’s the temperature now? Here, we have 5 – 3 = 2. The answer is 2 degrees Celsius.
These examples illustrate how adding and subtracting integers can help us solve practical problems and better understand the world. We encourage you to find your examples and practice to enhance your understanding and mastery of this fundamental mathematical skill.
As the journey of discovery with integers continues, multiplication and division of these numbers become an integral part of our everyday mathematical activities. Understanding how to tackle word problems – mathematical problems in narrative form – becomes critical. Specifically, multiplication and division integer word problems provide the groundwork for applying knowledge practically in real-world situations.
Multiplying integers might initially seem complex , but it becomes straightforward once you grasp the core concept. When multiplying two integers, the result will be positive if the signs are the same (positive or negative). However, if the signs are different (positive and negative), the result will be a negative integer.
Dividing integers follows a similar concept. If the integers have the same sign, the quotient is positive, and if they have different signs, it is negative.
Now, let’s see how these concepts apply in real-world scenarios. Suppose a person has $20 and wants to buy as many chocolates as possible, with each chocolate bar costing $4. In this case, they’d need to divide 20 by 4. The question boils down to 20 ÷ 4, which equals 5. So, they can buy five chocolate bars.
Considering multiplication, imagine a scenario where a store sells packages of bottled drinking water. Each package contains six bottles, and the store has twenty packages. To calculate the total number of bottles, you would multiply 6 (bottles per package) by 20 (number of packages), getting 6 x 20 = 120. So, the store has 120 bottled water.
These real-world examples show how multiplication and division word problems offer practical ways to understand and apply mathematical knowledge. Engaging with these problems enhances understanding of fundamental math concepts and promotes problem-solving skills crucial for daily life.
In a journey through mathematics, we commonly encounter complex multi-step word problems. These problems often involve multiple operations using integers , such as addition, subtraction, multiplication, and division. Solving these tasks enhances problem-solving skills, logical thinking, and mathematical proficiency. This part will delve into complex integer word problems and introduce strategies for solving multi-step problems.
Complex integer word problems involve more than one mathematical operation, often requiring a systematic approach to reach the solution. For instance, imagine a scenario where a garden filled with 120 roses and petunias is being prepared for a garden show. There are twice as many roses as there are petunias. The question is, “How many petunias are there?”
Here, the problem will be solved in two steps. First, understanding that the number of roses is twice that of petunias. That means, if we denote the number of petunias as ‘p,’ then the number of roses is ‘2p’. The total quantity of flowers (120) is the sum of roses and petunias, leading to the equation 2p + p = 120. Solving this equation provides the number of petunias. Since multi-step word problems rely heavily on integers, understanding their operation rules is essential.
Solving multi-step word problems can seem daunting, but a systematic approach simplifies the task. Below are vital strategies:
Remember, practice significantly improves problem-solving skills and the ability to tackle complex multi-step word problems involving integers. Happy problem-solving!
In particular, integer word problems can sometimes throw you off course. Like every journey, it is customary to make mistakes along the way. However, understanding and learning from these common errors can help you avoid detours and get you on the fast track to mastery.
Misinterpretation is one of the most common mistakes when handling integer word problems. Often, students need to understand the operations required or interpret the relationship between the integers presented in the problem.
Inaccurate Calculations – Integers include both positive and negative numbers, and it is easy to miscalculate when it comes to subtraction, addition, or other operations involving such numbers. For example, subtracting a negative integer leads to an addition instead.
Once you’re aware of common pitfalls, arm yourself with the right strategies to navigate your way through complex integer word problems adeptly.

An arithmetic operation is an elementary branch of mathematics. Arithmetical operations include addition, subtraction, multiplication and division. Arithmetic operations are applicable to different types of numbers including integers.
Integers are a special group of numbers that do not have a fractional or a decimal part. It includes positive numbers, negative numbers and zero. Arithmetic operations on integers are similar to that of whole numbers. Since integers can be positive or negative numbers i.e. as these numbers are preceded either by a positive (+) or a negative sign (-), it makes them a little confusing concept. Therefore, they are different from whole numbers . Let us now see how various arithmetical operations can be performed on integers with the help of a few word problems. Solve the following word problems using various rules of operations of integers.
Example 1: Shyak has overdrawn his checking account by Rs.38. The bank debited him Rs.20 for an overdraft fee. Later, he deposited Rs.150. What is his current balance?
Solution: Given,
Total amount deposited= Rs. 150
Amount overdrew by Shyak= Rs. 38
Amount charged by bank= Rs. 20
⇒ Debit amount= -20
Total amount debited = (-38) + (-20) = -58
Current balance= Total deposit +Total Debit
Hence, the current balance is Rs. 92.
Example 2: Anna is a microbiology student. She was doing research on optimum temperature for the survival of different strains of bacteria. Studies showed that bacteria X need optimum temperature of -31˚C while bacteria Y need optimum temperature of -56˚C. What is the temperature difference?
Solution: Given,
Optimum temperature for bacteria X = -31˚C
Optimum temperature for bacteria Y= -56˚C
Temperature difference= Optimum temperature for bacteria X – Optimum temperature for bacteria Y
⇒ (-31) – (-56)
Hence, temperature difference is 25˚C.
Example 3: A submarine submerges at the rate of 5 m/min. If it descends from 20 m above the sea level, how long will it take to reach 250 m below sea level?
Initial position = 20 m (above sea level)
Final position = 250 m (below sea level)
Total depth it submerged = (250+20) = 270 m
Thus, the submarine travelled 270 m below sea level.
Time taken to submerge 1 meter = 1/5 minutes
Time taken to submerge 270 m = 270 (1/5) = 54 min
Hence, the submarine will reach 250 m below sea level in 54 minutes.

For solving integer word problems students need the right base of knowledge on integers. Proper practice is required for solving integer questions correctly. In this article, we will help students develop the base required for answering word problems on integers for Class 7.
Let’s start with the fact that an arithmetic operation is an elementary branch of mathematics. Arithmetic operations are subtraction, addition, division, and multiplication. These arithmetic operations are used for solving integer problems. There are also other types of numbers that can be solved with the help of arithmetic operations.
It should also be noted that integers are a special group that does not contain any decimal or fractional part. Integers include positive numbers, negative numbers, and zero . Also, arithmetic operations on integers are similar to whole numbers .
It also makes it a little confusing to solve word problems on integers for class 6 and word problems on integers for class 7 pdf because there are both positive and negative numbers. This is also why integers are different from whole numbers.
Integers can also be plotted on a number line. A number line might also be used by students when learning how to solve integers questions. These types of questions are more common when it comes to integers word problems Class 7. If you have never seen a number line, then an image of a number line is attached below.
There are several rules that students need for learning how to solve integer word problems. Some of those rules are mentioned below.
The sum of any two positive integers will result in an integer.
The sum of any two negative integers is an integer.
The product of two positive integers will give an integer.
The product of two negative integers will be given an integer.
The sum of any integer and its inverse will be equal to zero.
The product of an integer and its reciprocal will be equal to 1.
Now, let’s look at addition, multiplication, subtraction, and division of signed integer numbers. This will help students to work on story problems with integers answer key.
As mentioned above, if we add two integers with the same sign, then we have to add the absolute value along with the sign that was provided with the number. For example, (+4) + (+7) = +11 and (-6) + (-4) = -10.
Also, if we add two integers with different signs, then we have to subtract the absolute values and write down the difference. This should be done with the sign of the number that has the largest absolute value. For example, (-4) + (+2) = -2 and (+6) + (-4) = +2.
If a student wants to solve integer example problems, then he or she needs to know that while subtracting two integers, we have to change the sign of the second number. The second number should be subtracted and the rules of addition should also be followed. For example, (-7) - (+4) = (-7) + (-4) = -11 and (+8) - (+3) = (+8) + (-3) = +5.
When it comes to working on integer word problems with solutions of multiplying and dividing two integer numbers, then the rules are quite straightforward. If both the integers have the same sign, then the final results are positive. If the integers have different signs, then the final result is negative. For example, (+2) x (+3) = +6, (+3) x (-4) = -12, (+6) / (+2) = +3, and (-16) / (+4) = -4.
Students should also be familiar with the properties of integers if they want to work on integer word problems grade 6 with solutions. Some of those properties of integers are:
Closure property
Associative property
Commutative property
Distributive property
Additive inverse property
Multiplicative inverse property
Identity property
We also need to look at these properties in detail for solving integer problems in 6th grade. Let’s move on to that discussion.
According to the closure property of integers, if two integers are added or multiplied together, the final result will be an integer only. This means that if a and b are integers, then:
a + b = integer
a x b = integer
For example, 2 + 5 = 7, which is an integer, and 2 x 5 = 10, which is also an integer.
According to this property, if a and b are two integers, then a + b = b + a and a x b = b x a. For example, 3 + 8 = 8 x 3 = 24 and 3 + 8 = 8 + 3 = 11. It should be noted that this property is not followed in the case of subtraction and division.
According to the associative property, if a, b, and c are integers, then:
a + (b + c) = (a + b) + c
a x (b x c) = (a x b) x c
For example, 2 + (3 + 4) = (2 + 3) + 4 = 9 and 2 x (3 x 4) = (2 x 3) x 4 = 24.
This property is only valid when it comes to addition and multiplication.
The distributive property states that if a, b, and c are integers, then a x (b + c) = a x b + a x c. For example, if we have to prove that 3 x (5 +1) = 3 x 5 + 3 x 1, then we should be start by finding:
LHS = 3 x (5 + 1) = 3 x 6 = 18
RHS = 3 x 5 + 3 x 1 = 15 + 3 = 18
Since, LHS = RHS
This proves our example.
This additive inverse property states that if a is an integer, then a + (-a) = 0. This means that-a is the additive inverse of integer a.
The multiplicative inverse property states that if a is an integer, then a x (1 / a) = 1. This means that 1 / a is the multiplicative inverse of integer a.
The identity property of integers states that a + 0 = a and a x 1 = a. For example, 4 + 0 = 4 and 4 x 1 = 4.
Earlier, we mentioned that there are three types of integers. In this section, we will look at these types of integers in more depth. The list of those types of integers is mentioned below.
Zero can be characterized as neither a positive nor a negative integer. It can be best defined as a neutral number. This also refers to the fact that zero has no sign (+ or -).
As the name indicates, positive integers are those numbers that are positive in their nature. These numbers are represented by a positive or plus (+) sign. The positive integers lie on the right side of the zero on the number line. This also means that all positive integers are greater than zero. For example, 122, 54, and 9087268292.
Negative integers, on the other hand, are numbers that are represented by a minus (-) or negative sign. These numbers are present on the left side of the zero on a number line. For example, -182, -8292, and -2927225.
The word integer comes from the Latin word “ integer ” which literally means whole.
You might find it interesting to note that integers are not just simple numbers on paper. Instead, these numbers have real-life applications! Both positive and negative integers are used to symbolize two contradicting situations in the real world. For example, if the temperature is above zero, then positive integers are used for denoting the temperature. But if the temperature is less than zero, then negative integers are used for denoting the temperature.
Integers can also help an individual in comparing and measuring two things like how small or big or few or more things are. These integers help in quantifying things. For example, in games like cricket and soccer, integers are used for keeping a track of scores. Movies and songs can also be rated by using integers!
1. What are integers and what is their importance?
An integer is usually defined as a number that can be written without any type of fractional component. These numbers tend to consist of zero, positive natural numbers or whole numbers, and their additive inverses. For example, 2, -56, 98, -302, etc. A set of integers is always denoted by the letter “Z”.
The concept of integers is quite an important one to learn in mathematics. This is mainly because integers tend to help us compute the efficiency in both negative as well as positive numbers in a wide range of fields. They also help us to facilitate a number of calculations that are imperative to our daily lives. For example, we use integers to describe the temperature above or below the freezing point, to debit or credit money, etc.
2. What are the rules for adding and subtracting integers?
There are some rules to be noted while adding two or more integers. They are as follows:
The sum of an integer and its additive inverse is always zero.
When you add two positive integers, the result will always be a positive number which will be greater than the two integers.
When you add two negative integers, the result will always be a negative number which will be smaller than the two integers you added.
By finding the difference between the absolute value of a positive integer and a negative one, you can add both of them. And the sign of the greater number out of the two will be attached to the end product.
When you add an integer with zero, you will get the same number as the answer.
There are some rules to be noted while subtracting two or more integers. They are as follows:
When you subtract any integer from zero, the answer will be either the additive inverse or the opposite of the integer. And when you subtract zero from any integer, then the result will always be the integer itself.
If you want to subtract two integers that have the same sign, you ought to perform a subtraction operation on the absolute values of those numbers.
If you want to subtract two integers that have different signs, you ought to add the absolute values.
3. State the principles that the addition and subtraction of integers on a number line is based on.
The principles upon which the addition of integers on a number line is based are as follows:
Moving towards the right or the positive side of the number line will lead to the addition of a positive integer.
Moving towards the left or the negative side of the number line will lead to the addition of a negative integer.
Any of the integers can be taken as the base point (the point from where you start to move on the number line).
The principles upon which the subtraction of integers on a number line is based are as follows:
Every subtraction fact can also be written as an addition fact.
Moving towards the left or the negative side of the number line will lead to the subtraction of a positive integer.
Moving towards the right or the positive side of the number line will lead to the subtraction of a negative integer.
4. Is multiplying rational numbers just like multiplying integers? If so, how?
To a certain extent, multiplying rational numbers is just like multiplying integers because the rules that are applicable to the latter, are also the same for the former. Rational numbers are just numbers that can be written in the fraction form of two given integers. So, if both the divisor and the dividend have the same signs, then the quotient will be positive. And if the divisor and the dividend have different signs, then the quotient will be negative.
5. Can integers be decimals?
No. Just like whole numbers, integers can neither be fractions, nor can they be decimals. All integers can be expressed as a decimal, however, most of the numbers that are decimals cannot be expressed as integers.
