    Column by column: 203 + 17

    • Ones: 3 + 7 = 10 — write 0, carry 1.
    • Tens: 0 + 1 + 1 = 2 — write 2.
    • Hundreds: nothing to add — write 2.

    203 + 17 = 220

    Second check: 220 − 203 = 17

    FAQ

    What is 203 + 17?

    203 + 17 = 220

    How do you check that 203 + 17 = 220?

    Subtract one addend from the sum: 220 − 17 = 203, and 220 − 203 = 17. Getting the other addend back means the sum is right.

    How many carries are there in 203 + 17?

    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 17 + 203 the same as 203 + 17?

    Yes. Addition is commutative, so both give 220; the column looks the same with either number on top.
