- Ones: 1 is less than 5 — borrow 1 hundred across the zero: hundreds 8 → 7, tens 0 → 9; 11 − 5 = 6 — write 6.
- Tens: after borrowing, 9; 9 − 4 = 5 — write 5.
- Hundreds: after borrowing, 7; 7 − 3 = 4 — write 4.
- Thousands: 5 − 2 = 3 — write 3.
- Ten thousands: 3 − 1 = 2 — write 2.
- Hundred thousands: nothing to subtract — write 1.
135,801 − 12,345 = 123,456
