15 Times Table
Fifteen is ten plus half of ten, so 15 × 8 is 80 plus 40, which is 120. The answers take turns ending in 5 and ending in 0, which makes a wrong answer easy to spot.
All facts of the 15 times table
Read the table aloud once, then cover the answers and say them from memory.
- 15 × 1 = 15
- 15 × 2 = 30
- 15 × 3 = 45
- 15 × 4 = 60
- 15 × 5 = 75
- 15 × 6 = 90
- 15 × 7 = 105
- 15 × 8 = 120
- 15 × 9 = 135

How to remember it
Times 15 is times 10 plus half of it: 15 × 8 = 80 + 40 = 120.
How to multiply by 15
- 15 = 10 + 5, and 5 is half of 10. Take 10 × n, then add half of that: 15 × 6 = 60 + 30 = 90.
- For odd numbers the half ends in 5: 15 × 7 = 70 + 35 = 105.
- The answers take turns ending in 5 and 0: 15, 30, 45, 60, 75 …
- Clock link: 15 minutes is a quarter of an hour, so 15 × 4 = 60 minutes.
Worked examples
15 × 8
- 10 × 8 = 80.
- Half of 80 is 40.
