SoonFrequently asked questions
Are both players given the same sums?
Yes. Every round deals one shared chain of additions, subtractions and small multiplications to both sides, in the same order. Nobody can draw an easier board - the race is decided purely by how fast you read and answer.
What happens when I tap a wrong answer in Math Sprint?
The board locks for a moment and then deals you a fresh sum. The lock is the real penalty: while you sit out, your opponent keeps solving, so a guess costs more than a second of honest thinking.
How hard is the arithmetic?
Deliberately light: two-digit additions and subtractions plus times-table multiplications. The duel is about speed of recall under pressure, not about paper-and-pencil skills - most sums take one to three seconds.
Does Math Sprint help mental arithmetic?
Racing a real person adds time pressure that solo drills lack, and repeated sprints make number facts automatic. It trains quick recall of sums the way a stopwatch trains a runner - short, intense and repeatable.
