647 + 63 = 710

How do you check that 647 + 63 = 710?

Subtract one addend from the sum: 710 − 63 = 647, and 710 − 647 = 63. Getting the other addend back means the sum is right.

How many carries are there in 647 + 63?

2 carries: every time a column added up to 10 or more, its ones digit was written and 1 was carried to the next column on the left.

Is 63 + 647 the same as 647 + 63?

Yes. Addition is commutative, so both give 710; the column looks the same with either number on top.
