    FAQ

    What is 12 + 12?

    12 + 12 = 24

    How do you check that 12 + 12 = 24?

    Subtract one addend from the sum: 24 − 12 = 12. Getting the other addend back means the sum is right.

    How many carries are there in 12 + 12?

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