    What is 155 − 19?

    Answer

    155 − 19 =
    136

    With regrouping: 1 borrow — from the tens

    155 − 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.
    4+10
    1 5(was 5, now 4)5 (was 5, now 15)
    −19
    136

    Column by column: 155 − 19

    • Ones: 5 is less than 9 — borrow 1 ten: tens 5 → 4; 15 − 9 = 6 — write 6.
    • Tens: after borrowing, 4; 4 − 1 = 3 — write 3.
    • Hundreds: nothing to subtract — write 1.

    155 − 19 = 136

    Second check: 155 − 136 = 19
