    FAQ

    What is 187 + 172?

    187 + 172 = 359

    How do you check that 187 + 172 = 359?

    Subtract one addend from the sum: 359 − 172 = 187, and 359 − 187 = 172. Getting the other addend back means the sum is right.

    How many carries are there in 187 + 172?

    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 172 + 187 the same as 187 + 172?

    Yes. Addition is commutative, so both give 359; the column looks the same with either number on top.
