    FAQ

    What is 389 + 256?

    389 + 256 = 645

    How do you check that 389 + 256 = 645?

    Subtract one addend from the sum: 645 − 256 = 389, and 645 − 389 = 256. Getting the other addend back means the sum is right.

    How many carries are there in 389 + 256?

    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 256 + 389 the same as 389 + 256?

    Yes. Addition is commutative, so both give 645; the column looks the same with either number on top.
