    FAQ

    What is 307 + 39?

    307 + 39 = 346

    How do you check that 307 + 39 = 346?

    Subtract one addend from the sum: 346 − 39 = 307, and 346 − 307 = 39. Getting the other addend back means the sum is right.

    How many carries are there in 307 + 39?

    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 39 + 307 the same as 307 + 39?

    Yes. Addition is commutative, so both give 346; the column looks the same with either number on top.
