    What is 86 − 17?

    Answer

    86 − 17 =
    69

    With regrouping: 1 borrow — from the tens

    86 − 17 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.
    7+10
    8(was 8, now 7)6 (was 6, now 16)
    −17
    69

    Column by column: 86 − 17

    • Ones: 6 is less than 7 — borrow 1 ten: tens 8 → 7; 16 − 7 = 9 — write 9.
    • Tens: after borrowing, 7; 7 − 1 = 6 — write 6.

    86 − 17 = 69

    Second check: 86 − 69 = 17
