    FAQ

    What is 34 + 12?

    34 + 12 = 46

    How do you check that 34 + 12 = 46?

    Subtract one addend from the sum: 46 − 12 = 34, and 46 − 34 = 12. Getting the other addend back means the sum is right.

    How many carries are there in 34 + 12?

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

    Is 12 + 34 the same as 34 + 12?

    Yes. Addition is commutative, so both give 46; the column looks the same with either number on top.
