    FAQ

    602 + 427 = 1,029

    How do you check that 602 + 427 = 1,029?

    Subtract one addend from the sum: 1,029 − 427 = 602, and 1,029 − 602 = 427. Getting the other addend back means the sum is right.

    How many carries are there in 602 + 427?

    1 carry: 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 427 + 602 the same as 602 + 427?

    Yes. Addition is commutative, so both give 1,029; the column looks the same with either number on top.
