    FAQ

    What is 427 + 402?

    427 + 402 = 829

    How do you check that 427 + 402 = 829?

    Subtract one addend from the sum: 829 − 402 = 427, and 829 − 427 = 402. Getting the other addend back means the sum is right.

    How many carries are there in 427 + 402?

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

    Is 402 + 427 the same as 427 + 402?

    Yes. Addition is commutative, so both give 829; the column looks the same with either number on top.
