Quick mental math speed test
Three quick problems, times, plus and minus: how fast can you pick the right answer?
Try a practice roundPlay today’s fiveHow it works
Three quick problems, a mix of times, plus and minus, like 7 × 8 or 34 + 19. Tap the right answer from four. A wrong answer, or one too quick to have worked it out, costs 1.5 s, and you keep going until you get it.
What it measures
Simple arithmetic draws on facts you have memorized, like times tables, and on quick working-memory calculation for sums and differences.
Speed here comes from recall and from checking the answers efficiently, not just from calculating.
What’s a good score?
In Reactdle, 1.8 s or faster rates Sharp, up to 2.6 s is Steady, and slower is Sluggish.
Tips
- Work out the answer before looking at the choices.
- Last digits are a fast check: 7 × 8 must end in 6.
