Because 641 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.

If you look closely at the last digit of each result, you will notice that it repeats in a cycle every few rows. Spotting these cycles is a simple way to build number sense and make multiplication feel more intuitive.

A quick way to generate these multiples on your own is to start from 641 × 10 and move up or down in steps of 641. For example, once you know 641 × 20, you can get 641 × 19 or × 21 by subtracting or adding one more block of 641.
