    • Tens: after borrowing, 1; 1 is less than 7 — borrow 1 hundred: hundreds 6 → 5; 11 − 7 = 4 — write 4.
    • Hundreds: after borrowing, 5; 5 − 5 = 0 — write 0.
    • Thousands: 1 is less than 3 — borrow 1 ten thousand: ten thousands 1 → 0; 11 − 3 = 8 — write 8.
    • Ten thousands: after borrowing, 0 — a leading zero is not written.
