Patterns that help you remember it

  • The last digits repeat in a cycle of 10: 9, 8, 7, 6, 5, 4, 3, 2, 1, 0.
  • Split it into tens and ones: 129 × k = 120 × k + 9 × k.
  • Each answer is 129 more than the one before, so you can count on in steps of 129.

Building it from tables you already know

To multiply 129 by 9, multiply by 10 and take one 129 away: 1,290 − 129 = 1,161. To multiply by 11, multiply by 10 and add one more 129: 1,290 + 129 = 1,419. Multiplying by 4 is doubling twice: 129 → 258 → 516.

Every multiple of 129 is at least 129, so there are none below 100 and 7 below 1,000. A number is in the 129 times table exactly when it divides by 129 with no remainder.

Odd, even and the last digit

Because 129 is odd, the answers alternate between odd and even: 129 × 1 = 129 is odd, 129 × 2 = 258 is even, and so on. Multiplying by 10 always puts a zero on the end: 129 × 10 = 1,290, and 129 × 100 = 12,900. Multiplying by 5 is half of multiplying by 10: half of 1,290 is 645.

Using the 129 times table to divide

Every fact also works backwards: because 129 × 7 = 903, you know 903 ÷ 129 = 7 and 903 ÷ 7 = 129. Practising the table and its division facts together halves the work.

Questions

What is 129 × 12?

1,548.

What is half of 129 × 8?

129 × 8 = 1,032, and half of that is 516, which is 129 × 4. Halving one factor halves the answer.

What is 129 times 0?

0. Any number multiplied by zero is zero, because zero groups of 129 contain nothing.

What is 129 × 7 and 129 × 8?

129 × 7 = 903 and 129 × 8 = 1,032. These two are the facts most people find hardest, so they are worth practising on their own.

Is 1,935 in the 129 times table?

Yes: 1,935 ÷ 129 = 15 with no remainder. 1,936 is not, because dividing it by 129 leaves a remainder of 1.

How do I learn the 129 times table quickly?

Learn it in order first, then use the patterns above and practise mixed questions; a few minutes a day works better than one long session.
