    FAQ

    What is 578 + 94?

    578 + 94 = 672

    How do you check that 578 + 94 = 672?

    Subtract one addend from the sum: 672 − 94 = 578, and 672 − 578 = 94. Getting the other addend back means the sum is right.

    How many carries are there in 578 + 94?

    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 94 + 578 the same as 578 + 94?

    Yes. Addition is commutative, so both give 672; the column looks the same with either number on top.
