    Column by column: 1,132 − 485

    • Ones: 2 is less than 5 — borrow 1 ten: tens 3 → 2; 12 − 5 = 7 — write 7.
    • Tens: after borrowing, 2; 2 is less than 8 — borrow 1 hundred: hundreds 1 → 0; 12 − 8 = 4 — write 4.
    • Hundreds: after borrowing, 0; 0 is less than 4 — borrow 1 thousand: thousands 1 → 0; 10 − 4 = 6 — write 6.
    • Thousands: after borrowing, 0 — a leading zero is not written.

    1,132 − 485 = 647

    Second check: 1,132 − 647 = 485
