How much do these lessons cost?

Purplemath's lessons cost nothing! These lessons are free, are intended for students (rather than for instructors), and are interlinked to help you find related material. There is a "Search" box on every page to help you find whatever math content you're looking for — without encountering ads masquerading as search results. Whether you're in middle school, high school, college, or university, these free algebra lessons can help you out!

How can I use Purplemath's lessons?

Purplemath's math lessons can be used in many ways:

• Read the lesson that relates to what you're about to study in class, so you get to class at least somewhat prepared.
• Print out the lesson that relates to what you're about to study in class, and use the margins, white space, or the backs of pages for taking notes in class.
• When the homework seems impossible and the textbook and your class notes aren't helping much, come to Purplemath for clarification.

Let Purplemath help you always be prepared!

How should I be formatting my homework?

Neat homework can aid your comprehension and might make your teacher like you better. Purplemath's " Homework Guidelines for Mathematics " will give you a leg up, explaining in clear terms what your math teacher is looking for. The Guidelines link to examples of common errors, and demonstrate techniques that your instructors will love! In addition, students who get in the habit of explaining themselves clearly in their homework gain greater understanding of what they're doing, and therefore tend to do much better on their tests.

English teachers tell their students explicitly how to format their papers: what fonts, what page margins, what style guides, etc. Math teachers, on the other hand, frequently just complain amongst themselves in the faculty lounge about how messy their students' work is. Meanwhile, their students wonder why they've lost points on homework and tests.

Study these Guidelines , print out this " formatting " PDF, and improve your learning, retention, and test scores. Don't leave easy points on the table!

Go to the Guidelines!

How can I measure my study skills?

Many students, from time to time, wonder, "Do I have what it takes to succeed in math?" Much of one's success or failure in algebra can be laid at the feet of one's study habits. Do you have good math study habits? Take this survey and find out.

IRS Tax Tip 2024-38, April 25, 2024

When a taxpayer realizes that their federal tax return has a math error, missing income or other mistake, they should file an amended tax return.

A taxpayer must file an amended return if they need to correct:

• Filing status.
• Deductions.
• Tax liability.

Math errors and missing schedules

Taxpayers usually do not need to file an amended return to fix a math error or if they forgot to attach a form or schedule. The IRS will correct the math error while processing the tax return and notify the taxpayer by mail. The agency will send a letter to request any missing forms or schedules.

The IRS Interactive Tax Assistant can help taxpayers decide if an amended return is necessary

Taxpayers can use the Should I file an amended return? tool in the Interactive Tax Assistant on IRS.gov to help decide if they should file an amended return to correct an error or make other changes if they already filed.

How to file an amended tax return

Taxpayers should use Form 1040-X, Amended U.S. Individual Income Tax Return , to correct a previously filed Form 1040-series return or to change amounts previously adjusted by the IRS. Taxpayers can file Form 1040-X electronically for their 2020, 2021, 2022 and 2023 Forms 1040 or 1040-SR. Additionally, they can electronically amend Form 1040-NR and Form 1040-SS/PR for tax years 2021, 2022 and 2023.

Check the status of an amended return

Taxpayers can check the status of their Form 1040-X with the Where's My Amended Return?  online tool or by calling 866-464-2050 three weeks after filing it. They can also check the status of their refund with the Where’s My Refund?  tool.

When using either tool, taxpayers will need to enter their Social Security or taxpayer identification number along with their date of birth and ZIP Code to prove their identity. Once authenticated, they can view the status of their amended return across three processing stages: received, adjusted and completed.

Some tax returns may take longer to process

The IRS issues most refunds in fewer than 21 days for taxpayers who filed electronically and choose direct deposit. Some returns have errors or need more review and may take longer to process.
