    FAQ

    What is 637 + 63?

    637 + 63 = 700

    How do you check that 637 + 63 = 700?

    Subtract one addend from the sum: 700 − 63 = 637, and 700 − 637 = 63. Getting the other addend back means the sum is right.

    How many carries are there in 637 + 63?

    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 63 + 637 the same as 637 + 63?

    Yes. Addition is commutative, so both give 700; the column looks the same with either number on top.
