4,988 + 12 = 5,000

How do you check that 4,988 + 12 = 5,000?

Subtract one addend from the sum: 5,000 − 12 = 4,988, and 5,000 − 4,988 = 12. Getting the other addend back means the sum is right.

How many carries are there in 4,988 + 12?

3 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 12 + 4,988 the same as 4,988 + 12?

Yes. Addition is commutative, so both give 5,000; the column looks the same with either number on top.
