    FAQ

    What is 427 + 203?

    427 + 203 = 630

    How do you check that 427 + 203 = 630?

    Subtract one addend from the sum: 630 − 203 = 427, and 630 − 427 = 203. Getting the other addend back means the sum is right.

    How many carries are there in 427 + 203?

    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 203 + 427 the same as 427 + 203?

    Yes. Addition is commutative, so both give 630; the column looks the same with either number on top.
