    What is 280 − 12?

    Answer

    280 − 12 =
    268

    With regrouping: 1 borrow — from the tens

    280 − 12 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.
    7+10
    2 8(was 8, now 7)0 (was 0, now 10)
    −12
    268

    Column by column: 280 − 12

    • Ones: 0 is less than 2 — borrow 1 ten: tens 8 → 7; 10 − 2 = 8 — write 8.
    • Tens: after borrowing, 7; 7 − 1 = 6 — write 6.
    • Hundreds: nothing to subtract — write 2.

    280 − 12 = 268

    Second check: 280 − 268 = 12
