    FAQ

    What is 203 + 187?

    203 + 187 = 390

    How do you check that 203 + 187 = 390?

    Subtract one addend from the sum: 390 − 187 = 203, and 390 − 203 = 187. Getting the other addend back means the sum is right.

    How many carries are there in 203 + 187?

    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 187 + 203 the same as 203 + 187?

    Yes. Addition is commutative, so both give 390; the column looks the same with either number on top.
