    What is 390 − 83?

    Answer

    390 − 83 =
    307

    With regrouping: 1 borrow — from the tens

    390 − 83 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.
    8+10
    3 9(was 9, now 8)0 (was 0, now 10)
    −83
    307

    Column by column: 390 − 83

    • Ones: 0 is less than 3 — borrow 1 ten: tens 9 → 8; 10 − 3 = 7 — write 7.
    • Tens: after borrowing, 8; 8 − 8 = 0 — write 0.
    • Hundreds: nothing to subtract — write 3.

    390 − 83 = 307

    Second check: 390 − 307 = 83
