    FAQ

    What is 485 + 415?

    485 + 415 = 900

    How do you check that 485 + 415 = 900?

    Subtract one addend from the sum: 900 − 415 = 485, and 900 − 485 = 415. Getting the other addend back means the sum is right.

    How many carries are there in 485 + 415?

    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 415 + 485 the same as 485 + 415?

    Yes. Addition is commutative, so both give 900; the column looks the same with either number on top.
