58 + 45 = 103

How do you check that 58 + 45 = 103?

Subtract one addend from the sum: 103 − 45 = 58, and 103 − 58 = 45. Getting the other addend back means the sum is right.

How many carries are there in 58 + 45?

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 45 + 58 the same as 58 + 45?

Yes. Addition is commutative, so both give 103; the column looks the same with either number on top.
