    FAQ

    What is 54 + 12?

    54 + 12 = 66

    How do you check that 54 + 12 = 66?

    Subtract one addend from the sum: 66 − 12 = 54, and 66 − 54 = 12. Getting the other addend back means the sum is right.

    How many carries are there in 54 + 12?

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

    Is 12 + 54 the same as 54 + 12?

    Yes. Addition is commutative, so both give 66; the column looks the same with either number on top.
