    FAQ

    What is 402 + 187?

    402 + 187 = 589

    How do you check that 402 + 187 = 589?

    Subtract one addend from the sum: 589 − 187 = 402, and 589 − 402 = 187. Getting the other addend back means the sum is right.

    How many carries are there in 402 + 187?

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

    Is 187 + 402 the same as 402 + 187?

    Yes. Addition is commutative, so both give 589; the column looks the same with either number on top.
