Patterns that help you remember it

  • The last digits repeat in a cycle of 2: 5, 0.
  • Every answer ends in 0 or 5.
  • Split it into tens and ones: 1145 × k = 1140 × k + 5 × k.
  • Each answer is 1145 more than the one before, so you can count on in steps of 1145.

Building it from tables you already know

To multiply 1145 by 9, multiply by 10 and take one 1145 away: 11,450 − 1145 = 10,305. To multiply by 11, multiply by 10 and add one more 1145: 11,450 + 1145 = 12,595. Multiplying by 4 is doubling twice: 1145 → 2,290 → 4,580.

Every multiple of 1145 is at least 1145, so there are none below 100 and 0 below 1,000. A number is in the 1145 times table exactly when it divides by 1145 with no remainder.

Odd, even and the last digit

Because 1145 is odd, the answers alternate between odd and even: 1145 × 1 = 1145 is odd, 1145 × 2 = 2,290 is even, and so on. Multiplying by 10 always puts a zero on the end: 1145 × 10 = 11,450, and 1145 × 100 = 114,500. Multiplying by 5 is half of multiplying by 10: half of 11,450 is 5,725.

Using the 1145 times table to divide

Every fact also works backwards: because 1145 × 7 = 8,015, you know 8,015 ÷ 1145 = 7 and 8,015 ÷ 7 = 1145. Practising the table and its division facts together halves the work.
