    FAQ

    What is 683 + 307?

    683 + 307 = 990

    How do you check that 683 + 307 = 990?

    Subtract one addend from the sum: 990 − 307 = 683, and 990 − 683 = 307. Getting the other addend back means the sum is right.

    How many carries are there in 683 + 307?

    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 307 + 683 the same as 683 + 307?

    Yes. Addition is commutative, so both give 990; the column looks the same with either number on top.
