    What is 131 − 39?

    Answer

    131 − 39 =
    92

    With regrouping: 2 borrows — from the tens and the hundreds

    131 − 39 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.

    −39
    92

    Column by column: 131 − 39

    • Ones: 1 is less than 9 — borrow 1 ten: tens 3 → 2; 11 − 9 = 2 — write 2.
    • Tens: after borrowing, 2; 2 is less than 3 — borrow 1 hundred: hundreds 1 → 0; 12 − 3 = 9 — write 9.
    • Hundreds: after borrowing, 0 — a leading zero is not written.

    131 − 39 = 92

    Second check: 131 − 92 = 39
