    FAQ

    What is 647 + 402?

    647 + 402 = 1,049

    How do you check that 647 + 402 = 1,049?

    Subtract one addend from the sum: 1,049 − 402 = 647, and 1,049 − 647 = 402. Getting the other addend back means the sum is right.

    How many carries are there in 647 + 402?

    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 402 + 647 the same as 647 + 402?

    Yes. Addition is commutative, so both give 1,049; the column looks the same with either number on top.
