    What is 178 − 89?

    Answer

    89

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

    178 − 89 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.

    1(was 1, now 0)7(was 7, now 16)8 (was 8, now 18)
    −89
    89

    Column by column: 178 − 89

    • Ones: 8 is less than 9 — borrow 1 ten: tens 7 → 6; 18 − 9 = 9 — write 9.
    • Tens: after borrowing, 6; 6 is less than 8 — borrow 1 hundred: hundreds 1 → 0; 16 − 8 = 8 — write 8.
    • Hundreds: after borrowing, 0 — a leading zero is not written.

    178 − 89 = 89
