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.
  • The digits of every answer add up to a multiple of 9.
  • Split it into tens and ones: 1989 × k = 1980 × k + 9 × k.
  • Each answer is 1989 more than the one before, so you can count on in steps of 1989.

Building it from tables you already know

To multiply 1989 by 9, multiply by 10 and take one 1989 away: 19,890 − 1989 = 17,901. To multiply by 11, multiply by 10 and add one more 1989: 19,890 + 1989 = 21,879. Multiplying by 4 is doubling twice: 1989 → 3,978 → 7,956.

Every multiple of 1989 is at least 1989, so there are none below 100 and 0 below 1,000. A number is in the 1989 times table exactly when it divides by 1989 with no remainder.

Odd, even and the last digit

Because 1989 is odd, the answers alternate between odd and even: 1989 × 1 = 1989 is odd, 1989 × 2 = 3,978 is even, and so on. Multiplying by 10 always puts a zero on the end: 1989 × 10 = 19,890, and 1989 × 100 = 198,900. Multiplying by 5 is half of multiplying by 10: half of 19,890 is 9,945.

Using the 1989 times table to divide

Every fact also works backwards: because 1989 × 7 = 13,923, you know 13,923 ÷ 1989 = 7 and 13,923 ÷ 7 = 1989. Practising the table and its division facts together halves the work.
