    FAQ

    What is 307 + 85?

    307 + 85 = 392

    How do you check that 307 + 85 = 392?

    Subtract one addend from the sum: 392 − 85 = 307, and 392 − 307 = 85. Getting the other addend back means the sum is right.

    How many carries are there in 307 + 85?

    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 85 + 307 the same as 307 + 85?

    Yes. Addition is commutative, so both give 392; the column looks the same with either number on top.
