Patterns that help you remember it

  • The last digits repeat in a cycle of 1: 0.
  • Every answer is even, because 400 is even.
  • Every answer ends in 0 or 5.
  • Split it into tens and ones: 400 × k = 400 × k + 0 × k.
  • Each answer is 400 more than the one before, so you can count on in steps of 400.

Building it from tables you already know

Every answer in the 400 times table is double the answer in the 200 times table: 200 × 6 = 1,200, so 400 × 6 = 2,400. To multiply 400 by 9, multiply by 10 and take one 400 away: 4,000 − 400 = 3,600. To multiply by 11, multiply by 10 and add one more 400: 4,000 + 400 = 4,400. Multiplying by 4 is doubling twice: 400 → 800 → 1,600.

Every multiple of 400 is at least 400, so there are none below 100 and 2 below 1,000. A number is in the 400 times table exactly when it divides by 400 with no remainder.

Odd, even and the last digit

Because 400 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: 400 × 10 = 4,000, and 400 × 100 = 40,000. Multiplying by 5 is half of multiplying by 10: half of 4,000 is 2,000.

Using the 400 times table to divide

Every fact also works backwards: because 400 × 7 = 2,800, you know 2,800 ÷ 400 = 7 and 2,800 ÷ 7 = 400. 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 400 pencils. How many pencils are in 4 boxes?
    Answer4 × 400 = 1,600 pencils.
  2. Tickets cost $400 each. How much do 9 tickets cost?
    Answer9 × $400 = $3,600.
  3. 3,200 chairs are set out in rows of 400. How many rows are there?
    Answer3,200 ÷ 400 = 8 rows.
  4. A plant grows 400 millimetres a week. How much does it grow in 9 weeks?
    Answer9 × 400 = 3,600 millimetres.

Questions

What is 400 × 12?

4,800.

What is half of 400 × 8?

400 × 8 = 3,200, and half of that is 1,600, which is 400 × 4. Halving one factor halves the answer.

What is 400 times 0?

0. Any number multiplied by zero is zero, because zero groups of 400 contain nothing.

What is 400 × 7 and 400 × 8?

400 × 7 = 2,800 and 400 × 8 = 3,200. These two are the facts most people find hardest, so they are worth practising on their own.

Is 6,000 in the 400 times table?

Yes: 6,000 ÷ 400 = 15 with no remainder. 6,001 is not, because dividing it by 400 leaves a remainder of 1.

How do I learn the 400 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.
