    FAQ

    What is 288 + 12?

    288 + 12 = 300

    How do you check that 288 + 12 = 300?

    Subtract one addend from the sum: 300 − 12 = 288, and 300 − 288 = 12. Getting the other addend back means the sum is right.

    How many carries are there in 288 + 12?

    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 12 + 288 the same as 288 + 12?

    Yes. Addition is commutative, so both give 300; the column looks the same with either number on top.
