    FAQ

    What is 468 + 172?

    468 + 172 = 640

    How do you check that 468 + 172 = 640?

    Subtract one addend from the sum: 640 − 172 = 468, and 640 − 468 = 172. Getting the other addend back means the sum is right.

    How many carries are there in 468 + 172?

    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 172 + 468 the same as 468 + 172?

    Yes. Addition is commutative, so both give 640; the column looks the same with either number on top.
