Patterns that help you remember it

  • The last digits repeat in a cycle of 10: 1, 2, 3, 4, 5, 6, 7, 8, 9, 0.
  • Split it into tens and ones: 311 × k = 310 × k + 1 × k.
  • Each answer is 311 more than the one before, so you can count on in steps of 311.

Building it from tables you already know

To multiply 311 by 9, multiply by 10 and take one 311 away: 3,110 − 311 = 2,799. To multiply by 11, multiply by 10 and add one more 311: 3,110 + 311 = 3,421. Multiplying by 4 is doubling twice: 311 → 622 → 1,244.

Every multiple of 311 is at least 311, so there are none below 100 and 3 below 1,000. A number is in the 311 times table exactly when it divides by 311 with no remainder.

Odd, even and the last digit

Because 311 is odd, the answers alternate between odd and even: 311 × 1 = 311 is odd, 311 × 2 = 622 is even, and so on. Multiplying by 10 always puts a zero on the end: 311 × 10 = 3,110, and 311 × 100 = 31,100. Multiplying by 5 is half of multiplying by 10: half of 3,110 is 1,555.

Using the 311 times table to divide

Every fact also works backwards: because 311 × 7 = 2,177, you know 2,177 ÷ 311 = 7 and 2,177 ÷ 7 = 311. Practising the table and its division facts together halves the work.

    Answer6 × 311 = 1,866 pencils.
  2. Tickets cost $311 each. How much do 7 tickets cost?
    Answer7 × $311 = $2,177.
  3. 1,866 chairs are set out in rows of 311. How many rows are there?
    Answer1,866 ÷ 311 = 6 rows.
  4. A plant grows 311 millimetres a week. How much does it grow in 6 weeks?

Questions

What is 311 × 12?

3,732.

What is half of 311 × 8?

311 × 8 = 2,488, and half of that is 1,244, which is 311 × 4. Halving one factor halves the answer.

What is 311 times 0?

0. Any number multiplied by zero is zero, because zero groups of 311 contain nothing.

What is 311 × 7 and 311 × 8?

311 × 7 = 2,177 and 311 × 8 = 2,488. These two are the facts most people find hardest, so they are worth practising on their own.

Is 4,665 in the 311 times table?

Yes: 4,665 ÷ 311 = 15 with no remainder. 4,666 is not, because dividing it by 311 leaves a remainder of 1.

How do I learn the 311 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.
