788 + 12 = 800

How do you check that 788 + 12 = 800?

Subtract one addend from the sum: 800 − 12 = 788, and 800 − 788 = 12. Getting the other addend back means the sum is right.

How many carries are there in 788 + 12?

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 12 + 788 the same as 788 + 12?

Yes. Addition is commutative, so both give 800; the column looks the same with either number on top.
