Describe how you regroup when you find the sum of 64 + 43

I would split 64 into 60 & 4, and 43  into 40 & 3

Than i would add the 60 and 40 together (which will give me 100)
I will than add 4 & 3 together (which will give me 7)

Than i will add 100 and 7 together, which will give me 107

107 is your final answer

hope this helps
