    FAQ

    What is 307 + 172?

    307 + 172 = 479

    How do you check that 307 + 172 = 479?

    Subtract one addend from the sum: 479 − 172 = 307, and 479 − 307 = 172. Getting the other addend back means the sum is right.

    How many carries are there in 307 + 172?

    None: no column adds up to 10 or more, so every digit of the sum is written straight away.

    Is 172 + 307 the same as 307 + 172?

    Yes. Addition is commutative, so both give 479; the column looks the same with either number on top.
