Patterns that help you remember it

  • The last digits repeat in a cycle of 1: 0.
  • Every answer is even, because 100 is even.
  • Every answer ends in 0 or 5.
  • Split it into tens and ones: 100 × k = 100 × k + 0 × k.
  • Each answer is 100 more than the one before, so you can count on in steps of 100.

Building it from tables you already know

Every answer in the 100 times table is double the answer in the 50 times table: 50 × 6 = 300, so 100 × 6 = 600. To multiply 100 by 9, multiply by 10 and take one 100 away: 1,000 − 100 = 900. To multiply by 11, multiply by 10 and add one more 100: 1,000 + 100 = 1,100. Multiplying by 4 is doubling twice: 100 → 200 → 400.

Every multiple of 100 is at least 100, so there are none below 100 and 9 below 1,000. A number is in the 100 times table exactly when it divides by 100 with no remainder.

Odd, even and the last digit

Because 100 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: 100 × 10 = 1,000, and 100 × 100 = 10,000. Multiplying by 5 is half of multiplying by 10: half of 1,000 is 500.

Using the 100 times table to divide

Every fact also works backwards: because 100 × 7 = 700, you know 700 ÷ 100 = 7 and 700 ÷ 7 = 100. 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 100 pencils. How many pencils are in 8 boxes?
    Answer8 × 100 = 800 pencils.
  2. Tickets cost $100 each. How much do 5 tickets cost?
    Answer5 × $100 = $500.
  3. 800 chairs are set out in rows of 100. How many rows are there?
    Answer800 ÷ 100 = 8 rows.
  4. A plant grows 100 millimetres a week. How much does it grow in 7 weeks?
    Answer7 × 100 = 700 millimetres.

Questions

What is 100 × 12?

1,200.

What is half of 100 × 8?

100 × 8 = 800, and half of that is 400, which is 100 × 4. Halving one factor halves the answer.

What is 100 times 0?

0. Any number multiplied by zero is zero, because zero groups of 100 contain nothing.

What is 100 × 7 and 100 × 8?

100 × 7 = 700 and 100 × 8 = 800. These two are the facts most people find hardest, so they are worth practising on their own.

Is 1,500 in the 100 times table?

Yes: 1,500 ÷ 100 = 15 with no remainder. 1,501 is not, because dividing it by 100 leaves a remainder of 1.

How do I learn the 100 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.
