Patterns that help you remember it

  • The last digits repeat in a cycle of 1: 0.
  • Every answer is even, because 20 is even.
  • Every answer ends in 0 or 5.
  • Split it into tens and ones: 20 × k = 20 × k + 0 × k.
  • Each answer is 20 more than the one before, so you can count on in steps of 20.

Building it from tables you already know

Every answer in the 20 times table is double the answer in the 10 times table: 10 × 6 = 60, so 20 × 6 = 120. To multiply 20 by 9, multiply by 10 and take one 20 away: 200 − 20 = 180. To multiply by 11, multiply by 10 and add one more 20: 200 + 20 = 220. Multiplying by 4 is doubling twice: 20 → 40 → 80.

There are 4 multiples of 20 below 100, and 49 below 1,000. A number is in the 20 times table exactly when it divides by 20 with no remainder.

Odd, even and the last digit

Because 20 is even, every answer in its table is even, which is a quick way to catch a wrong answer. Multiplying by 10 always puts a zero on the end: 20 × 10 = 200, and 20 × 100 = 2,000. Multiplying by 5 is half of multiplying by 10: half of 200 is 100.

Using the 20 times table to divide

Every fact also works backwards: because 20 × 7 = 140, you know 140 ÷ 20 = 7 and 140 ÷ 7 = 20. Practising the table and its division facts together halves the work.

Word problems

Times tables are most useful when you can spot them in a question. Try these, then open each one to check:

  1. A box holds 20 pencils. How many pencils are in 4 boxes?
    Answer4 × 20 = 80 pencils.
  2. Tickets cost $20 each. How much do 9 tickets cost?
    Answer9 × $20 = $180.
  3. 140 chairs are set out in rows of 20. How many rows are there?
    Answer140 ÷ 20 = 7 rows.
  4. A plant grows 20 millimetres a week. How much does it grow in 9 weeks?
    Answer9 × 20 = 180 millimetres.

Questions

What is 20 × 12?

240.

What is half of 20 × 8?

20 × 8 = 160, and half of that is 80, which is 20 × 4. Halving one factor halves the answer.

What is 20 times 0?

0. Any number multiplied by zero is zero, because zero groups of 20 contain nothing.

What is 20 × 7 and 20 × 8?

20 × 7 = 140 and 20 × 8 = 160. These two are the facts most people find hardest, so they are worth practising on their own.

Is 300 in the 20 times table?

Yes: 300 ÷ 20 = 15 with no remainder. 301 is not, because dividing it by 20 leaves a remainder of 1.

How do I learn the 20 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.
