    What is 250 − 78?

    Answer

    250 − 78 =
    172

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

    250 − 78 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.
    114+10
    2(was 2, now 1)5(was 5, now 14)0 (was 0, now 10)
    −78
    172

    Column by column: 250 − 78

    • Ones: 0 is less than 8 — borrow 1 ten: tens 5 → 4; 10 − 8 = 2 — write 2.
    • Tens: after borrowing, 4; 4 is less than 7 — borrow 1 hundred: hundreds 2 → 1; 14 − 7 = 7 — write 7.
    • Hundreds: after borrowing, 1; nothing to subtract — write 1.

    250 − 78 = 172

    Second check: 250 − 172 = 78
