# What is math used for?

## Have you ever said, “Why do I have to learn math? I’m never going to use it!”

Well, the truth is if you learn math, you can use it all the time. Most people who don’t use math in their everyday lives CAN’T use it because they never really learned it.

Sometimes students think math (and algebra in particular) is just something made up to torture students, and that it has no practical value at all. NOT TRUE!

Math (and even algebra) is used in almost every aspect of the world.

Did you know the Pythagorean Theorem is what makes it possible for rooms and buildings to have perfectly square corners?

Have you ever tried to decide which cell phone plan is best for you? Algebra can help you do that.

Do you want to start your own business? Algebra can help you determine if you can make a profit.

Have you ever wondered what grade you need to get on a final exam to get the grade you want in the class? Yep. Algebra.

Do you play video games? We wouldn’t have video games without algebra. (And your HDTV relies on mathematics, too)

You can even use algebra to predict how fast a rumor will spread.

Amazing.
