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

You don’t need to regroup

To regroup, you simply break up the bigger numbers into smaller numbers that are more easily added together. We often regroup numbers into numbers that end with 0 because they're easier to add. For example, you can break up 64into 60+4 and 43 into 40+3. This will make addition easier, because you can first add together 60 and 40, which is equal to 100. Then, you can add the smaller digits 100+4+3=107.
