    FAQ

    What is 602 + 578?

    602 + 578 = 1,180

    How do you check that 602 + 578 = 1,180?

    Subtract one addend from the sum: 1,180 − 578 = 602, and 1,180 − 602 = 578. Getting the other addend back means the sum is right.

    How many carries are there in 602 + 578?

    2 carries: every time a column added up to 10 or more, its ones digit was written and 1 was carried to the next column on the left.

    Is 578 + 602 the same as 602 + 578?

    Yes. Addition is commutative, so both give 1,180; the column looks the same with either number on top.
