    FAQ

    What is 47 + 28?

    47 + 28 = 75

    How do you check that 47 + 28 = 75?

    Subtract one addend from the sum: 75 − 28 = 47, and 75 − 47 = 28. Getting the other addend back means the sum is right.

    How many carries are there in 47 + 28?

    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 28 + 47 the same as 47 + 28?

    Yes. Addition is commutative, so both give 75; the column looks the same with either number on top.
