Because 45 is an odd number, the multiples alternate between odd and even results. This is a useful trick when you quickly want to check if a result “looks right” without doing the full calculation again.
Multiples of 45 often end in 0 or 5, which is why they show up so often in money and measurement problems. You can use this pattern to estimate answers in your head before you write them down.
A quick way to generate these multiples on your own is to start from 45 × 10 and move up or down in steps of 45. For example, once you know 45 × 20, you can get 45 × 19 or × 21 by subtracting or adding one more block of 45.
