    FAQ

    What is 65 + 12?

    65 + 12 = 77

    How do you check that 65 + 12 = 77?

    Subtract one addend from the sum: 77 − 12 = 65, and 77 − 65 = 12. Getting the other addend back means the sum is right.

    How many carries are there in 65 + 12?

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

    Is 12 + 65 the same as 65 + 12?

    Yes. Addition is commutative, so both give 77; the column looks the same with either number on top.
