    • Tens: after borrowing, 0; 0 is less than 5 — borrow 1 hundred: hundreds 1 → 0; 10 − 5 = 5 — write 5.
    • Hundreds: after borrowing, 0; 0 is less than 4 — borrow 1 thousand: thousands 1 → 0; 10 − 4 = 6 — write 6.
    • Thousands: after borrowing, 0; 0 is less than 3 — borrow 1 ten thousand: ten thousands 1 → 0; 10 − 3 = 7 — write 7.
    • Ten thousands: after borrowing, 0; 0 is less than 2 — borrow 1 hundred thousand: hundred thousands 1 → 0; 10 − 2 = 8 — write 8.
