    What is 322 − 15?

    Answer

    322 − 15 =
    307

    With regrouping: 1 borrow — from the tens

    322 − 15 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.
    1+10
    3 2(was 2, now 1)2 (was 2, now 12)
    −15
    307

    Column by column: 322 − 15

    • Ones: 2 is less than 5 — borrow 1 ten: tens 2 → 1; 12 − 5 = 7 — write 7.
    • Tens: after borrowing, 1; 1 − 1 = 0 — write 0.
    • Hundreds: nothing to subtract — write 3.

    322 − 15 = 307

    Second check: 322 − 307 = 15
