Were you a mental math athlete, or mathlete, in school? Has it been a while since you flexed your mental math muscles? If you think you've still got what it takes to ace a mental math challenge, take this quiz to find out how much you really remember!

We know that you've probably heard of the national spelling bee, but did you know that there are similar competitions at various levels (city, state, regional, national, etc.) for kids who excel in math? Well, it's true. Just in case you weren't a nerd in school, or you didn't hang out with nerds, there are actual competitions where students go to compete with other math geniuses. OK, so most of them aren't geniuses, but they certainly have mastered some pretty cool ways to perform mathematical equations in their heads. These kids are called "mathletes" these days, and they gather regularly to practice those snazzy mental calculations and to compete against one another before heading off to a regional, or even national, competition.

So, if you were one of those nerds, we've got a quiz to bring back some, hopefully good, memories. If not, we've sneaked some simple tricks into this quiz to help you learn how solve these equations without a calculator.

Let's find out how much mental math power you still have!
