    FAQ

    What is 63 + 17?

    63 + 17 = 80

    How do you check that 63 + 17 = 80?

    Subtract one addend from the sum: 80 − 17 = 63, and 80 − 63 = 17. Getting the other addend back means the sum is right.

    How many carries are there in 63 + 17?

    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 17 + 63 the same as 63 + 17?

    Yes. Addition is commutative, so both give 80; the column looks the same with either number on top.
