    What is 725 − 78?

    Answer

    725 − 78 =
    647

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

    725 − 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.
    611+10
    7(was 7, now 6)2(was 2, now 11)5 (was 5, now 15)
    −78
    647

    Column by column: 725 − 78

    • Ones: 5 is less than 8 — borrow 1 ten: tens 2 → 1; 15 − 8 = 7 — write 7.
    • Tens: after borrowing, 1; 1 is less than 7 — borrow 1 hundred: hundreds 7 → 6; 11 − 7 = 4 — write 4.
    • Hundreds: after borrowing, 6; nothing to subtract — write 6.

    725 − 78 = 647

    Second check: 725 − 647 = 78
