Speed Maths

A minute of sums — add, subtract, multiply and divide, or just the one you want to drill. The next sum arrives the moment you answer, and a run of right answers multiplies your points.

Speed Maths is a minute of mental arithmetic. Sums arrive one at a time — 37 + 48, 9 × 7, 84 ÷ 12 — and the next appears the moment you answer. Play all four operations mixed, or drill the one you want to get faster at.

How to play Speed Maths

Choose the operations — all four, or just one — and a level, which sets how big the numbers are.
Type the answer. There is no Enter: an answer is judged the moment it has as many digits as the right one.
A wrong answer clears and the same sum waits for you. Pass skips it and shows the answer.
You have one minute.

Scoring

Each sum is worth points by its operation, more on harder levels.
A run of right answers builds a combo that multiplies your points; a wrong answer or a pass breaks it.

No clock

Choose No clock to play twenty sums, however long they take. A wrong answer still only breaks your combo, and a no-clock game keeps its own best, apart from the minute’s.

Tips

Add in two steps: 37 + 48 is 37 + 50, then take away 2.
Division always comes out whole, so think of it as the times table backwards.

Play it with friends

On your own, against the characters — each plays the game by its own rules the moment it starts, so there is always somebody to beat.
With friends, each on their own phone or laptop: one of you shows a code, the others type it in, and everybody gets exactly the same game on the same Go.
Taking turns on one device — pass it round, and each turn is scored against the turns before.
