    FAQ

    What is 485 + 12?

    485 + 12 = 497

    How do you check that 485 + 12 = 497?

    Subtract one addend from the sum: 497 − 12 = 485, and 497 − 485 = 12. Getting the other addend back means the sum is right.

    How many carries are there in 485 + 12?

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

    Is 12 + 485 the same as 485 + 12?

    Yes. Addition is commutative, so both give 497; the column looks the same with either number on top.
