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

What we are going to do is use the DISTRIBUTIVE PROPERTY. This distributive the numbers, to make it easier to solve.

So we will break 64 up.

64 = 60 + 4

43 = 40 + 3

60 + 40 = 100

4 + 3 = 7

100 + 7 = 107

So, 64 + 43 = 107.

Hope I helped ya

You would first add the 4+3, and then you would add the 6+4. There is no need to regroup in this equation.
