    Column by column: 12,847 − 4,805

    • Ones: 7 − 5 = 2 — write 2.
    • Tens: 4 − 0 = 4 — write 4.
    • Hundreds: 8 − 8 = 0 — write 0.
    • Thousands: 2 is less than 4 — borrow 1 ten thousand: ten thousands 1 → 0; 12 − 4 = 8 — write 8.
    • Ten thousands: after borrowing, 0 — a leading zero is not written.

    12,847 − 4,805 = 8,042
