    What is 86 − 28?

    Answer

    86 − 28 =
    58

    With regrouping: 1 borrow — from the tens

    86 − 28 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)
    −28
    58

    Column by column: 86 − 28

    • Ones: 6 is less than 8 — borrow 1 ten: tens 8 → 7; 16 − 8 = 8 — write 8.
    • Tens: after borrowing, 7; 7 − 2 = 5 — write 5.

    86 − 28 = 58

    Second check: 86 − 58 = 28
