The 20 times table from 1 to 20
20 sits beyond the standard 12 × 12 chart, but its multiples come up constantly — a twenty is worth 20 dollars. Each row also gives the division fact it answers.
| Fact | Answer | Division fact |
|---|---|---|
| 20 × 1 | 20 | 20 ÷ 20 = 1 |
| 20 × 2 | 40 | 40 ÷ 20 = 2 |
| 20 × 3 | 60 | 60 ÷ 20 = 3 |
| 20 × 4 | 80 | 80 ÷ 20 = 4 |
| 20 × 5 | 100 | 100 ÷ 20 = 5 |
| 20 × 6 | 120 | 120 ÷ 20 = 6 |
| 20 × 7 | 140 | 140 ÷ 20 = 7 |
| 20 × 8 | 160 | 160 ÷ 20 = 8 |
| 20 × 9 | 180 | 180 ÷ 20 = 9 |
| 20 × 10 | 200 | 200 ÷ 20 = 10 |
| 20 × 11 | 220 | 220 ÷ 20 = 11 |
| 20 × 12 | 240 | 240 ÷ 20 = 12 |
| 20 × 13 | 260 | 260 ÷ 20 = 13 |
| 20 × 14 | 280 | 280 ÷ 20 = 14 |
| 20 × 15 | 300 | 300 ÷ 20 = 15 |
| 20 × 16 | 320 | 320 ÷ 20 = 16 |
| 20 × 17 | 340 | 340 ÷ 20 = 17 |
| 20 × 18 | 360 | 360 ÷ 20 = 18 |
| 20 × 19 | 380 | 380 ÷ 20 = 19 |
| 20 × 20 | 400 | 400 ÷ 20 = 20 |
Patterns in the 20 times table
- Last digits. Every answer ends in 0.
- Even answers. 20 is even, so every product in its table is even.
- Digit sums. Reduce each answer to a single digit (20 × 1 to 20 × 9 give 2, 4, 6, 8, 1, 3, 5, 7, 9) and all nine values appear before repeating.
- Built from a smaller table. 20 = 2 × 10, so every answer is double the matching answer in the 10 times table: 20 × 7 = 2 × 70 = 140.
- Split by place value. 20 × k = 10 × k + 10 × k, so 20 × 13 = 130 + 130 = 260.
A shortcut for multiplying by 20
Double, then write a zero on the end: 20 × 13 → 26 → 260.
Worked example: 20 × 7
Split 20 into 10 + 10: 10 × 7 = 70 and 10 × 7 = 70, so 20 × 7 = 140.
