The 11 times table looks scary but is surprisingly easy. For 11 × 1 through 11 × 9, you just write the digit twice: 11 × 3 = 33, 11 × 7 = 77. Only from 11 × 10 onwards does it get a touch trickier.
| Calculation | Answer |
|---|---|
| 11 × 1 | 11 |
| 11 × 2 | 22 |
| 11 × 3 | 33 |
| 11 × 4 | 44 |
| 11 × 5 | 55 |
| 11 × 6 | 66 |
| 11 × 7 | 77 |
| 11 × 8 | 88 |
| 11 × 9 | 99 |
| 11 × 10 | 110 |
| 11 × 11 | 121 |
| 11 × 12 | 132 |
Write the digit twice (up to × 9)
11 × 1 = 11, 11 × 2 = 22, 11 × 3 = 33, and so on up to 11 × 9 = 99. For every single digit 1 through 9, you simply write it twice side by side.
10 times plus one more
11 × a number = 10 × that number + the number itself. 11 × 7 = 70 + 7 = 77. 11 × 12 = 120 + 12 = 132. Works for every number.
The pattern changes from × 10
11 × 10 = 110, 11 × 11 = 121, 11 × 12 = 132. The simple 'write twice' trick stops here. Use 10 × X + X instead.
Children typically learn the multiplication tables in Grades 2 and 3 (ages 7–9). The tables of 2, 5 and 10 are taught first, then 3, 4 and 6, and finally the harder tables of 7, 8 and 9. Most children know all tables up to 10 by the end of Grade 3.
What is 11 × 11?+
11 × 11 = 121. Not via the 'write twice' trick (that only works up to × 9). Compute: 10 × 11 + 11 = 110 + 11 = 121.
Why does the 'write twice' trick work?+
Because 11 = 10 + 1. For single digits, that means the tens place becomes the digit itself and the ones place stays that same digit. 11 × 4 = 40 + 4 = 44 — hence 'twice the same'.
Is the 11 times table hard?+
No — up to 11 × 9 it is actually one of the easiest. 11 × 11 and 11 × 12 are trickier and need to be learned separately or computed via 10 × X + X.
What grade do children learn the 11 times table?+
The 11 times table is sometimes introduced in Grade 4 as an extension to the basic tables.
