User reviews

Never good at math, I'd forget a lot of x-+÷, so Challenge, Custom modes great for ÷ practice; color options help poor vision, Relax good workout but it would be a help to have a guide to area locations and if+-×÷, or +&-.

I originally got this app to help teach my kindergartener basic arithmetic, and now it is my own go to game. The app is simple and runs exceptionally well. I love the challenge and relax options. It has made my own mental math so much faster. The education tab is simple and easy to understand. If anyone wants to learn how to use an abacus or soroban, this is the perfect way to do it.
