308 + 92 = 400

How do you check that 308 + 92 = 400?

Subtract one addend from the sum: 400 − 92 = 308, and 400 − 308 = 92. Getting the other addend back means the sum is right.

How many carries are there in 308 + 92?

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 92 + 308 the same as 308 + 92?

Yes. Addition is commutative, so both give 400; the column looks the same with either number on top.
