    FAQ

    What is 71 + 23?

    71 + 23 = 94

    How do you check that 71 + 23 = 94?

    Subtract one addend from the sum: 94 − 23 = 71, and 94 − 71 = 23. Getting the other addend back means the sum is right.

    How many carries are there in 71 + 23?

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

    Is 23 + 71 the same as 71 + 23?

    Yes. Addition is commutative, so both give 94; the column looks the same with either number on top.
