Use the hundred square to find 10 less than 63.

We see that 63 has a red circle around it. And we need 10 less than 63. On a hundred square, to take less means to move to the left. If we move to the left one place, we go from 63 to 62.

To find 10 less than 63, let’s go backwards 10 spaces: one, two, three, four, five, six, seven, eight, nine, and 10. 53 is 10 less than 63. It’s just above it on a hundred square. That makes 53 10 less than 63.
