Answer 1

The first step in adding on hundred chart is find 27 and go down once because that would be ten. Then you have to go 2 numbers to the right because you already had a 10 and if you add 2 it will be 12. And we are doing addition. If you are doing a subtraction problem all you have to do is go up on how many tens you are going to subtract and go left if you have ones numbers. Hope it helps.
