Question

How do you regroup when you find the sum of 64 +43

Answer 1

Here, regrouping is basically carrying. 64+43 shown vertically would be: 64 +43 ------- 107 4+3 is 7, so seven is in the ones place, but that's not the point. 60+40 is 100, so you regroup by carrying the one to the hundreds place.
