    FAQ

    What is 34 + 23?

    34 + 23 = 57

    How do you check that 34 + 23 = 57?

    Subtract one addend from the sum: 57 − 23 = 34, and 57 − 34 = 23. Getting the other addend back means the sum is right.

    How many carries are there in 34 + 23?

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

    Is 23 + 34 the same as 34 + 23?

    Yes. Addition is commutative, so both give 57; the column looks the same with either number on top.
