| Fact | Answer | Division |
|---|---|---|
| 15 × 1 | 15 | 15 ÷ 15 = 1 |
| 15 × 2 | 30 | 30 ÷ 15 = 2 |
| 15 × 3 | 45 | 45 ÷ 15 = 3 |
| 15 × 4 | 60 | 60 ÷ 15 = 4 |
| 15 × 5 | 75 | 75 ÷ 15 = 5 |
| 15 × 6 | 90 | 90 ÷ 15 = 6 |
| 15 × 7 | 105 | 105 ÷ 15 = 7 |
| 15 × 8 | 120 | 120 ÷ 15 = 8 |
| 15 × 9 | 135 | 135 ÷ 15 = 9 |
| 15 × 10 | 150 | 150 ÷ 15 = 10 |
| 15 × 11 | 165 | 165 ÷ 15 = 11 |
| 15 × 12 | 180 | 180 ÷ 15 = 12 |
The trick: ten times plus half of that
15 × n = 10 × n + half of it: 15 × 8 = 80 + 40 = 120. Answers end in 5 or 0, alternating.
Patterns in the 15s
The last digits repeat a short cycle — 5, 0, 5, 0, 5, 0, 5, 0, 5, 0 — so every answer ends in one of 0, 5.
The 15 times table is the 10 times table plus the 5 times table, row by row: 15 × 6 = 10 × 6 + 5 × 6 = 60 + 30 = 90.
Each answer is 15 more than the one before, so if you know 15 × 6 = 90, then 15 × 7 is 90 + 15 = 105.
