The 2 times table from 1 to 20
2 × 1 through 2 × 9 belong to the core facts — every product of two one-digit numbers — that US standards expect students to know from memory by the end of third grade. Each row also gives the matching division fact.
| Fact | Answer | Division fact |
|---|---|---|
| 2 × 1 | 2 | 2 ÷ 2 = 1 |
| 2 × 2 | 4 | 4 ÷ 2 = 2 |
| 2 × 3 | 6 | 6 ÷ 2 = 3 |
| 2 × 4 | 8 | 8 ÷ 2 = 4 |
| 2 × 5 | 10 | 10 ÷ 2 = 5 |
| 2 × 6 | 12 | 12 ÷ 2 = 6 |
| 2 × 7 | 14 | 14 ÷ 2 = 7 |
| 2 × 8 | 16 | 16 ÷ 2 = 8 |
| 2 × 9 | 18 | 18 ÷ 2 = 9 |
| 2 × 10 | 20 | 20 ÷ 2 = 10 |
| 2 × 11 | 22 | 22 ÷ 2 = 11 |
| 2 × 12 | 24 | 24 ÷ 2 = 12 |
| 2 × 13 | 26 | 26 ÷ 2 = 13 |
| 2 × 14 | 28 | 28 ÷ 2 = 14 |
| 2 × 15 | 30 | 30 ÷ 2 = 15 |
| 2 × 16 | 32 | 32 ÷ 2 = 16 |
| 2 × 17 | 34 | 34 ÷ 2 = 17 |
| 2 × 18 | 36 | 36 ÷ 2 = 18 |
| 2 × 19 | 38 | 38 ÷ 2 = 19 |
| 2 × 20 | 40 | 40 ÷ 2 = 20 |
Patterns in the 2 times table
- Last digits. The ones digits repeat every 5 steps: 2, 4, 6, 8, 0, then 2, 4, 6, 8, 0 again. Only 5 different endings ever appear.
- Even answers. 2 is even, so every product in its table is even.
- Digit sums. Reduce each answer to a single digit (2 × 1 to 2 × 9 give 2, 4, 6, 8, 1, 3, 5, 7, 9) and all nine values appear before repeating.
A shortcut for multiplying by 2
Doubling: add the number to itself. Every answer is even, and the last digits cycle 2, 4, 6, 8, 0.
Worked example: 2 × 14
Split 14 into 10 + 4: 2 × 10 = 20 and 2 × 4 = 8, so 2 × 14 = 28.

Related to the 2 times table
- 2 × 2 = 4, so the square root of 4 is 2.
- The factors of 2 are 1 and 2; they pair up as 1 × 2, so 2 appears as an answer in each of those tables.
- Every answer in this table is a multiple of 2; the multiples calculator lists them past × 20.
Frequently asked questions
What is the 2 times table up to 12?
2 × 1 = 2, 2 × 2 = 4, 2 × 3 = 6, 2 × 4 = 8, 2 × 5 = 10, 2 × 6 = 12, 2 × 7 = 14, 2 × 8 = 16, 2 × 9 = 18, 2 × 10 = 20, 2 × 11 = 22, 2 × 12 = 24.
What is the easiest way to learn the 2 times table?
Doubling: add the number to itself. Every answer is even, and the last digits cycle 2, 4, 6, 8, 0.
What is 2 times 20?
2 × 20 = 40. Multiply 2 by 2 to get 4, then write a zero on the end.
Where is the 2 times table used in real life?
Any time you count equal groups of 2: a pair is 2 socks, so the socks in several pairs of socks come straight from the 2 times table.
