    What is 251 − 12?

    Answer

    251 − 12 =
    239

    With regrouping: 1 borrow — from the tens

    251 − 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.
    4+10
    2 5(was 5, now 4)1 (was 1, now 11)
    −12
    239

    Column by column: 251 − 12

    • Ones: 1 is less than 2 — borrow 1 ten: tens 5 → 4; 11 − 2 = 9 — write 9.
    • Tens: after borrowing, 4; 4 − 1 = 3 — write 3.
    • Hundreds: nothing to subtract — write 2.

    251 − 12 = 239

    Second check: 251 − 239 = 12
