    FAQ

    What is 578 + 34?

    578 + 34 = 612

    How do you check that 578 + 34 = 612?

    Subtract one addend from the sum: 612 − 34 = 578, and 612 − 578 = 34. Getting the other addend back means the sum is right.

    How many carries are there in 578 + 34?

    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 34 + 578 the same as 578 + 34?

    Yes. Addition is commutative, so both give 612; the column looks the same with either number on top.
