    FAQ

    What is 664 + 136?

    664 + 136 = 800

    How do you check that 664 + 136 = 800?

    Subtract one addend from the sum: 800 − 136 = 664, and 800 − 664 = 136. Getting the other addend back means the sum is right.

    How many carries are there in 664 + 136?

    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 136 + 664 the same as 664 + 136?

    Yes. Addition is commutative, so both give 800; the column looks the same with either number on top.
