Math Speed
Who calculates fastest? Solve math problems before your opponents!
How to Play
Goal
Solve math problems faster than your opponents and collect the most points.
Gameplay
All players see the same question at the same time. Type the answer and press Enter.
Points
First correct = 10 pts, second = 7, third = 5, others = 3. Wrong = 0 points.
Winner
After all rounds, the player with the most points wins.
Strategy & tips
Decompose instead of calculating. 17 times 6 is hard; 17 times 3 times 2 is easy. Splitting a large problem into two small steps is almost always faster mentally than attacking it directly.
Round and correct. 48 plus 37 becomes 50 plus 37 minus 2. The technique costs an extra step, but every individual step is trivial — and trivial steps happen without thinking.
Learn the patterns that keep recurring. Squares up to 25, the powers of ten, doubling and halving. With those building blocks ready to hand you stop calculating most problems and start recalling them.
Variants
Single operation
A round of multiplication or division only. Good for drilling a specific weakness.
Time penalty
Wrong answers cost seconds rather than just points, which makes guessing unattractive.
Escalating
Problems grow with every correct answer. The game ends when your head stops keeping up.

Origin
Mental arithmetic was a publicly performed art for centuries. Nineteenth-century calculating prodigies appeared on stage and solved multi-digit multiplications faster than the audience could write them down.
Research shows these feats rarely rest on faster calculation and almost always on a larger stock of memorised intermediate results. Speed here is mostly a question of memory.
Frequently asked questions
Which operations appear?
The four basic operations in varying order, with numbers that stay manageable in your head.
How many players can join?
Several at once — everyone gets the same problems and races in parallel.
Is it suitable for children?
Yes, it works well for practice. Because everyone gets identical problems, you can see exactly where you stand.
