About Mental Math Quiz
No calculator, no paper: the Mental Math Quiz serves ten quick sums a day to solve in your head and race your own best time. The first four are adding and subtracting up to a hundred, the middle three bring multiplication, division, bigger sums and easy percentages, and the last three ask for two-digit multiplication, squares, the order of operations and harder percentages. The questions are made fresh by the computer each day, so they never run out, and the wrong answers are near misses, so a guess rarely works. Each explanation shows a quick way to work the answer out.
How to play Mental Math Quiz
- Press Start for the first of ten questions. The clock starts with it and stops at your last answer.
- Each question is a sum to work out in your head: adding, subtracting, multiplying, dividing or a percentage.
- Tap an answer, or press 1 to 4 (or A to D) on a keyboard. Answers are final: you see the right one and a one-line explanation, then press Next.
- Most correct answers ranks first, then the fastest time. Only a member’s first finished quiz of the day counts for the leaderboard.
Tips & strategy
- Round and adjust: 49 + 36 is 50 + 36 minus 1, and 19 × 7 is 20 × 7 minus 7.
- Split two-digit multiplication into tens and units: 23 × 14 is 23 × 10 plus 23 × 4.
- For percentages, find 10% first by moving the decimal point, then double, halve or add.
