    FAQ

    What is 647 + 78?

    647 + 78 = 725

    How do you check that 647 + 78 = 725?

    Subtract one addend from the sum: 725 − 78 = 647, and 725 − 647 = 78. Getting the other addend back means the sum is right.

    How many carries are there in 647 + 78?

    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 78 + 647 the same as 647 + 78?

    Yes. Addition is commutative, so both give 725; the column looks the same with either number on top.
