Mental Math

Mental arithmetic that feels like a game. An exercise sits on a chip in the middle — 7 + 5, 9 × 8 + 4, √144. Drag it onto the right answer on the board before the clock runs out. Land it and your combo grows, taking the multiplier up to ×3. Miss and you only lose the combo: nothing here breaks. HOW IT PLAYS • 14 seconds per exercise, shown by the ring around the chip: green, then amber, then red • Answer early and score more — the bonus follows those exact colours • Three correct answers in a row lift the multiplier one step • Eight exercises per chapter, up to three stars — fewer misses, more stars • No exercise repeats inside a run TWELVE CHAPTERS 1. Adding to 20 2. Adding to 50 3. Missing addends 4. Subtraction 5. Missing subtrahends 6. Times tables 7. Division 8. Square numbers 9. Square roots 10. Big numbers 11. Order of operations 12. Everything mixed FOR PARENTS • No ads, no purchases, no accounts, no sign-up • No cross-app tracking, no advertising ID — only anonymous statistics and crash reports, so we can find bugs • Works fully offline — the app needs no internet and asks for no permissions • Progress stays on the device and never leaves it Made for primary and lower secondary school, for anyone getting their mental arithmetic back up to speed — and everyone in between.
