    What is 104 − 12?

    Answer

    104 − 12 =
    92

    With regrouping: 1 borrow — from the hundreds

    104 − 12 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)4
    −12
    92

    Column by column: 104 − 12

    • Ones: 4 − 2 = 2 — write 2.
    • Tens: 0 is less than 1 — borrow 1 hundred: hundreds 1 → 0; 10 − 1 = 9 — write 9.
    • Hundreds: after borrowing, 0 — a leading zero is not written.

    104 − 12 = 92

    Second check: 104 − 92 = 12
