11 times table, repeat the digit.

The 11 times table is 11, 22, 33, 44, 55, 66, 77, 88, 99, 110, 121, 132 up to 11 × 12. The first nine facts are the digit repeated, and the trick extends to two-digit numbers. The tool above shows the table, hides answers, runs a scored quiz with a hint for every wrong answer, and prints a chart or sheet.

How to use the 11 times table tool

1. Click Table to see the facts, the patterns for this number and the skip counting line. Go up to shows the table to 10, 12, 15 or 20.
2. Tick Hide the answers to test yourself. Tap a row to reveal its answer.
3. Click Practice quiz, then Start the quiz. Type each answer and press Enter. A wrong answer shows a quick way to work it out.
4. Under Quiz questions choose 10, 20, 30 or every fact once. Tick Ask both ways round or Include division to make the quiz harder.
5. At the end, read your score and click Practise the missed ones to go over only the facts you got wrong.
6. Use Print table for a clean sheet, Print practice sheet for a blank one, Copy table to paste the list, and Copy link to share your settings.

The 11 times table, 1 to 12

Repeat the digit

11 × 1 = 11, 11 × 2 = 22, and so on up to 11 × 9 = 99. These answers read the same forwards and backwards. The ones digit goes 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 and then 1 again, repeating every ten steps.

After 99

The next three break the repeat: 11 × 10 = 110, 11 × 11 = 121, 11 × 12 = 132. Each step adds 11, which raises the middle digit by 1 and the last digit by 1, so the answers read 110, 121, 132.

The two-digit trick

To multiply a two-digit number by 11, write the first digit, then the sum of the two digits, then the last digit. 11 × 34 gives 3, 7, 4, which is 374. 11 × 52 gives 5, 7, 2, which is 572. If the sum is 10 or more, carry the 1: for 11 × 78, the middle is 7 + 8 = 15, so write 7, 5, 8 and carry the 1 into the 7. That makes 858. For 11 × 99 the middle is 18, giving 9, 18, 9, which becomes 1,089.

Divisible by 11

Subtract and add the digits alternately from the left. For 121: 1 minus 2 plus 1 = 0, so 121 is in the table. For 2,728: 2 minus 7 plus 2 minus 8 = minus 11, which is a multiple of 11, so 2,728 = 11 × 248. If the result is 0 or a multiple of 11, the number is in the table.

Worked examples

• Team sheets. 11 players in each of 7 teams make 11 × 7 = 77 players.
• Two digits. 11 × 43: write 4, then 4 + 3 = 7, then 3. The answer is 473.
• Division. 99 ÷ 11 = 9, because 11 × 9 = 99.
• Missing number. 11 × ? = 132. The answer is 12.
• Past 12. 11 × 15 = 165 and 11 × 20 = 220.

Beyond 12: 11 × 13 to 11 × 20

Set Go up to to 20 and the tool shows these as well. For any of them, split the number: 11 × 13 is 11 × 10 plus 11 × 3, which is 110 + 33 = 143.

Common mistakes

• Writing 11 × 10 as 1010 or 111. It is 110.
• Forgetting to carry in the two-digit trick: 11 × 78 is 858, not 7158.
• Writing 11 × 12 as 122. It is 132.

A way to learn it

The first nine facts take a minute. Then learn 110, 121 and 132 as a set. Try the two-digit trick on a few numbers, and use the quiz to check you have the last three.

Next, try the 12 times table, or go back to the 10 times table. To see every table in one grid, use the times tables chart. To make your own cards, try the flashcard maker.
