    What is 191 − 19?

    Answer

    191 − 19 =
    172

    With regrouping: 1 borrow — from the tens

    191 − 19 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
    1 9(was 9, now 8)1 (was 1, now 11)
    −19
    172

    Column by column: 191 − 19

    • Ones: 1 is less than 9 — borrow 1 ten: tens 9 → 8; 11 − 9 = 2 — write 2.
    • Tens: after borrowing, 8; 8 − 1 = 7 — write 7.
    • Hundreds: nothing to subtract — write 1.

    191 − 19 = 172

    Second check: 191 − 172 = 19
