    FAQ

    What is 647 + 291?

    647 + 291 = 938

    How do you check that 647 + 291 = 938?

    Subtract one addend from the sum: 938 − 291 = 647, and 938 − 647 = 291. Getting the other addend back means the sum is right.

    How many carries are there in 647 + 291?

    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 291 + 647 the same as 647 + 291?

    Yes. Addition is commutative, so both give 938; the column looks the same with either number on top.
