A fast, adaptive arithmetic workout. Free, in your browser, no signup to start.
A math problem shows up — addition, subtraction, multiplication or division.
Work it out in your head and answer before the clock runs out.
Answer well and the numbers grow; slip up and the level eases back down.
Train each operation on its own, or switch to Mix mode, which shuffles all four so you can't predict what's next.
Part of the BrainScale training suite, trained by people in 120+ countries since 2011.
Mental Math is a timed arithmetic exercise: solve addition, subtraction, multiplication and division problems entirely in your head, with no pen, paper, or calculator. Each round asks you to work quickly and accurately, and the difficulty follows your performance — the numbers grow larger and the carries and borrows get trickier as you improve.
Regular short sessions beat occasional long ones — consistency is what moves your level.

Yes. Mental Math is free to play with no signup required to start. Creating a free account adds progress tracking and streaks; a premium plan removes free-tier session limits.
Each problem uses a level made of two digit-length settings, one per operand. Solve problems correctly and quickly, and the digit counts grow, so numbers get larger and carries/borrows get harder to track mentally. Slip up, and the level eases back down automatically.
Addition, subtraction, multiplication and division, each trainable on its own, plus a Mix mode that shuffles all four operations together so you cannot predict which one is coming next.
Short, frequent sessions beat occasional long ones. A few focused minutes a day is enough to keep pushing your level up, and pairs well with a daily training streak.
