    Column by column: 128,261 − 4,805

    • Ones: 1 is less than 5 — borrow 1 ten: tens 6 → 5; 11 − 5 = 6 — write 6.
    • Tens: after borrowing, 5; 5 − 0 = 5 — write 5.
    • Hundreds: 2 is less than 8 — borrow 1 thousand: thousands 8 → 7; 12 − 8 = 4 — write 4.
    • Thousands: after borrowing, 7; 7 − 4 = 3 — write 3.
    • Ten thousands: nothing to subtract — write 2.
    • Hundred thousands: nothing to subtract — write 1.

    128,261 − 4,805 = 123,456
