    What is 105 − 34?

    Answer

    105 − 34 =
    71

    With regrouping: 1 borrow — from the hundreds

    105 − 34 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.
    0+10
    1(was 1, now 0)0 (was 0, now 10)5
    −34
    71

    Column by column: 105 − 34

    • Ones: 5 − 4 = 1 — write 1.
    • Tens: 0 is less than 3 — borrow 1 hundred: hundreds 1 → 0; 10 − 3 = 7 — write 7.
    • Hundreds: after borrowing, 0 — a leading zero is not written.

    105 − 34 = 71

    Second check: 105 − 71 = 34
