    FAQ

    What is 63 + 12?

    63 + 12 = 75

    How do you check that 63 + 12 = 75?

    Subtract one addend from the sum: 75 − 12 = 63, and 75 − 63 = 12. Getting the other addend back means the sum is right.

    How many carries are there in 63 + 12?

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

    Is 12 + 63 the same as 63 + 12?

    Yes. Addition is commutative, so both give 75; the column looks the same with either number on top.
