    Column by column: 203 + 28

    • Ones: 3 + 8 = 11 — write 1, carry 1.
    • Tens: 0 + 2 + 1 = 3 — write 3.
    • Hundreds: nothing to add — write 2.

    203 + 28 = 231

    Second check: 231 − 203 = 28

    FAQ

    What is 203 + 28?

    203 + 28 = 231

    How do you check that 203 + 28 = 231?

    Subtract one addend from the sum: 231 − 28 = 203, and 231 − 203 = 28. Getting the other addend back means the sum is right.

    How many carries are there in 203 + 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 + 203 the same as 203 + 28?

    Yes. Addition is commutative, so both give 231; the column looks the same with either number on top.
