All High School mathematics students are familiar with learning and memorizing new formulas. There are hundreds of formulas, postulates, and theorems that they are expected to understand and implement on homework, quizzes, and tests. But should students memorize all of them? What are the most important math formulas to know?

# Important High School Math Formulas by Topic

## Algebra

The most important algebraic math formulas to know for are the ones for slope, slope-intercept form, midpoint, and the ever-famous quadratic formula. These four formulas are needed in each year of high school mathematics.

A Grade Ahead offers classes to help students master these formulas in Algebra 1

## Statistics & Probability

Statistics and probability topics are covered in nearly every mathematics course. Students can also take them as separate courses in most high schools (showing the significance of the topic). Furthermore, standardized tests love to include questions about them. That’s why knowing how to find the mean (average) and the likelihood of an event happening are crucial to success on these tests.

## Geometry

Geometry is the topic containing the most math formulas. It’s a subject that makes some students feel overwhelmed by thanks to all of formulas, theorems, and postulates. If you are one of those students, don’t worry! Here are the most important formulas for Geometry.

A Grade Ahead offers classes to help students develop mastery of Geometry principles as well.

For high school students, these formulas are the most important math formulas to know. Students who understand and can put into practice these formulas are more likely to succeed in the classroom and on standardized testing, especially the ACT/SAT.

This really helped me out a lot. I am in 8th grade and learning all of these concepts at my school already. Looks like I’m prepared for high school afterall!

It’s great

I’m not really good in mathematics formula but with this I felt good ..

My mom got me a book about high school math in the basics of algebra and I did not know any of this but I am so happy.

I’m in 6th Grade, in my class we’re not learning these type of things, but i want to be ready for the future. So i will be ready for anything that comes up! 🙂
