Memath is a mental-math game you can play in short sessions. Numbers and operators appear one symbol at a time, each replacing the last. Keep a running total and type your answer before the timer runs out.
7 plus 4. It sums up to 11, easy enough. Now subtract 2. Are you still holding 9 when the multiplication sign flashes up? That moment is what makes Memath fun. Each symbol disappears as the next one arrives.
Think it’ll be easy? The numbers get bigger, the rounds get longer, and there’s less time to think. You’re keeping the rhythm, calculating, holding the running total in your head, and thinking back a few steps to spot a shortcut, all at once.
But getting it right feels so good.
Learn the rhythm in a guided tutorial, then play “Campaign”. Each level gives you ten rounds to earn up to three stars. For a shorter session, try a five-round “Warm-up”.
Want to see how far you can go? Take on the boss at the end of each tier, see how long you can last on three lives in “Endless”, or build a level around the operator that keeps tripping you up.
Want more? Create your own levels: choose the operators, number range, number count and speed, and decide whether to include negative numbers. Stats show how accurate you are with each operator, so you can spend a few rounds on the one that needs practice.
Every expression is calculated strictly from left to right, with no operator precedence. So 7 + 4 − 2 × 3 means ((7 + 4) − 2) × 3, which is 27, not 5.
It is how a running total works anyway, one symbol at a time. After every round, the result screen shows the expression with brackets, so you always see how the answer was reached.
Play “Campaign” levels in four tiers, from “Easy” to “Expert”, with a boss level at the end of each tier. Every level is ten rounds, and you earn up to three stars.
Take on “Endless” with three lives and expressions that get harder as you go. Beat your best score.
Build your own levels. Choose the operators, the number range, the number count, the speed and whether negative totals are allowed.

Memath calculates strictly left to right, like a running total: 7 + 4 = 11, 11 − 2 = 9, 9 × 3 = 27. × and ÷ do not go first. Read more in the Help
