Mental Math Test
This mental math test shows one equation at a time. Tap true or false before the timer runs out. The time limit shrinks with every answer, and multiplication appears after a few rounds.
How it works
- Tap Play to see the first equation.
- Tap the right side if it is true and the left side if it is false.
- Answer before the bar runs out. One wrong answer ends the test.
Good to know
- Check the last digit first. It often tells you the answer quickly.
- Wrong answers are usually off by one, two or ten.
- Speed matters more as the time limit shrinks.
