    What is 281 − 78?

    Answer

    281 − 78 =
    203

    With regrouping: 1 borrow — from the tens

    281 − 78 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)1 (was 1, now 11)
    −78
    203

    Column by column: 281 − 78

    • Ones: 1 is less than 8 — borrow 1 ten: tens 8 → 7; 11 − 8 = 3 — write 3.
    • Tens: after borrowing, 7; 7 − 7 = 0 — write 0.
    • Hundreds: nothing to subtract — write 2.

    281 − 78 = 203

    Second check: 281 − 203 = 78
