    FAQ

    What is 74 + 15?

    74 + 15 = 89

    How do you check that 74 + 15 = 89?

    Subtract one addend from the sum: 89 − 15 = 74, and 89 − 74 = 15. Getting the other addend back means the sum is right.

    How many carries are there in 74 + 15?

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

    Is 15 + 74 the same as 74 + 15?

    Yes. Addition is commutative, so both give 89; the column looks the same with either number on top.
