    FAQ

    What is 578 + 12?

    578 + 12 = 590

    How do you check that 578 + 12 = 590?

    Subtract one addend from the sum: 590 − 12 = 578, and 590 − 578 = 12. Getting the other addend back means the sum is right.

    How many carries are there in 578 + 12?

    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 12 + 578 the same as 578 + 12?

    Yes. Addition is commutative, so both give 590; the column looks the same with either number on top.
