    FAQ

    What is 683 + 647?

    683 + 647 = 1,330

    How do you check that 683 + 647 = 1,330?

    Subtract one addend from the sum: 1,330 − 647 = 683, and 1,330 − 683 = 647. Getting the other addend back means the sum is right.

    How many carries are there in 683 + 647?

    3 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 647 + 683 the same as 683 + 647?

    Yes. Addition is commutative, so both give 1,330; the column looks the same with either number on top.
