172 + 36 = 208

How do you check that 172 + 36 = 208?

Subtract one addend from the sum: 208 − 36 = 172, and 208 − 172 = 36. Getting the other addend back means the sum is right.

How many carries are there in 172 + 36?

1 carry: 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 36 + 172 the same as 172 + 36?

Yes. Addition is commutative, so both give 208; the column looks the same with either number on top.
