Mental Math: Learn 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
