    Column by column: 1,294 − 647

    • Ones: 4 is less than 7 — borrow 1 ten: tens 9 → 8; 14 − 7 = 7 — write 7.
    • Tens: after borrowing, 8; 8 − 4 = 4 — write 4.
    • Hundreds: 2 is less than 6 — borrow 1 thousand: thousands 1 → 0; 12 − 6 = 6 — write 6.
    • Thousands: after borrowing, 0 — a leading zero is not written.

    1,294 − 647 = 647
