    FAQ

    What is 602 + 307?

    602 + 307 = 909

    How do you check that 602 + 307 = 909?

    Subtract one addend from the sum: 909 − 307 = 602, and 909 − 602 = 307. Getting the other addend back means the sum is right.

    How many carries are there in 602 + 307?

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

    Is 307 + 602 the same as 602 + 307?

    Yes. Addition is commutative, so both give 909; the column looks the same with either number on top.
