    What is 172 − 67?

    Answer

    172 − 67 =
    105

    With regrouping: 1 borrow — from the tens

    172 − 67 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.
    6+10
    1 7(was 7, now 6)2 (was 2, now 12)
    −67
    105

    Column by column: 172 − 67

    • Ones: 2 is less than 7 — borrow 1 ten: tens 7 → 6; 12 − 7 = 5 — write 5.
    • Tens: after borrowing, 6; 6 − 6 = 0 — write 0.
    • Hundreds: nothing to subtract — write 1.

    172 − 67 = 105

    Second check: 172 − 105 = 67
