    Column by column: 1,392,721 − 405,067

    • Ones: 1 is less than 7 — borrow 1 ten: tens 2 → 1; 11 − 7 = 4 — write 4.
    • Tens: after borrowing, 1; 1 is less than 6 — borrow 1 hundred: hundreds 7 → 6; 11 − 6 = 5 — write 5.
    • Hundreds: after borrowing, 6; 6 − 0 = 6 — write 6.
    • Thousands: 2 is less than 5 — borrow 1 ten thousand: ten thousands 9 → 8; 12 − 5 = 7 — write 7.
    • Ten thousands: after borrowing, 8; 8 − 0 = 8 — write 8.
    • Hundred thousands: 3 is less than 4 — borrow 1 million: millions 1 → 0; 13 − 4 = 9 — write 9.
    • Millions: after borrowing, 0 — a leading zero is not written.
