    What is 10,929 − 3,579?

    Answer

    10,929 − 3,579 =
    7,350

    With regrouping: 2 borrows — from the hundreds and the ten thousands

    10,929 − 3,579 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.
    0+108+10
    1(was 1, now 0)0 (was 0, now 10)9(was 9, now 8)2 (was 2, now 12)9
    −3579
    7350

    Column by column: 10,929 − 3,579

    • Ones: 9 − 9 = 0 — write 0.
    • Tens: 2 is less than 7 — borrow 1 hundred: hundreds 9 → 8; 12 − 7 = 5 — write 5.
    • Hundreds: after borrowing, 8; 8 − 5 = 3 — write 3.
    • Thousands: 0 is less than 3 — borrow 1 ten thousand: ten thousands 1 → 0; 10 − 3 = 7 — write 7.
    • Ten thousands: after borrowing, 0 — a leading zero is not written.

    10,929 − 3,579 = 7,350

    Second check: 10,929 − 7,350 = 3,579
