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

    1,330 − 647 = 683
