    What is 330 − 23?

    Answer

    330 − 23 =
    307

    With regrouping: 1 borrow — from the tens

    330 − 23 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.
    2+10
    3 3(was 3, now 2)0 (was 0, now 10)
    −23
    307

    Column by column: 330 − 23

    • Ones: 0 is less than 3 — borrow 1 ten: tens 3 → 2; 10 − 3 = 7 — write 7.
    • Tens: after borrowing, 2; 2 − 2 = 0 — write 0.
    • Hundreds: nothing to subtract — write 3.

    330 − 23 = 307

    Second check: 330 − 307 = 23
