    FAQ

    What is 1,515 + 485?

    1,515 + 485 = 2,000

    How do you check that 1,515 + 485 = 2,000?

    Subtract one addend from the sum: 2,000 − 485 = 1,515, and 2,000 − 1,515 = 485. Getting the other addend back means the sum is right.

    How many carries are there in 1,515 + 485?

    3 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 485 + 1,515 the same as 1,515 + 485?

    Yes. Addition is commutative, so both give 2,000; the column looks the same with either number on top.
