How it works

Equations

Pick a fighter, choose Equations, and trust your numbers. The faster and cleaner you solve, the harder you hit — from gentle early grades all the way to Olympic-level challenges.

An equation is a balance scale: whatever's on the left weighs the same as the right. The x is a mystery number, and your job is to get it alone.

For x + 4 = 11, undo the +4 by subtracting 4 from BOTH sides → x = 7. Whatever you do to one side, do to the other so the scale stays level.

Type the value of x.
