BASICS: Be Square
There are certain things in life you should just have committed to memory: your phone number, your mom’s birthday, the lyrics to I Will Survive, your squares up to 20.
Knowing your squares by heart will save you a ton of time when you’re square-rooting perfect squares and not-so-perfect squares, solving the Pythagorean Theorem, graphing parabolas, and more. When you’re working on a tougher skill, having the basic ones down will make things that much easier on you. And don’t you like when things are easy?
If you don’t know your squares up to 20, don’t sweat. We’ve included them below, and created a nifty worksheet for you to drill ‘em. Print out ours, make your own, or just rip out a piece of notebook paper and get to work. Before you begin, turn on some motivating tunes. We’re loving the new HAIM album.
