    FAQ

    What is 203 + 78?

    203 + 78 = 281

    How do you check that 203 + 78 = 281?

    Subtract one addend from the sum: 281 − 78 = 203, and 281 − 203 = 78. Getting the other addend back means the sum is right.

    How many carries are there in 203 + 78?

    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 78 + 203 the same as 203 + 78?

    Yes. Addition is commutative, so both give 281; the column looks the same with either number on top.
