    What is 510 − 203?

    Answer

    510 − 203 =
    307

    With regrouping: 1 borrow — from the tens

    510 − 203 in a column. Above the columns: the values after borrowing — a crossed-out digit is replaced by the number above it; +10 marks a column that received a borrowed ten.
    0+10
    5 1(was 1, now 0)0 (was 0, now 10)
    −203
    307

    Column by column: 510 − 203

    • Ones: 0 is less than 3 — borrow 1 ten: tens 1 → 0; 10 − 3 = 7 — write 7.
    • Tens: after borrowing, 0; 0 − 0 = 0 — write 0.
    • Hundreds: 5 − 2 = 3 — write 3.

    510 − 203 = 307

    Second check: 510 − 307 = 203
