    What is 1,032,743 − 45,089?

    Answer

    1,032,743 − 45,089 =
    987,654

    With regrouping across a zero: 5 borrows — there are no hundred thousands to borrow from, so 1 million becomes 10 hundred thousands, and 1 hundred thousand goes to the ten thousands

    1,032,743 − 45,089 in a column. Above the columns: the values after borrowing — a crossed-out digit is replaced by the number above it; +10 marks a column that received a borrowed ten.

    Column by column: 1,032,743 − 45,089

    • Ones: 3 is less than 9 — borrow 1 ten: tens 4 → 3; 13 − 9 = 4 — write 4.
    • Tens: after borrowing, 3; 3 is less than 8 — borrow 1 hundred: hundreds 7 → 6; 13 − 8 = 5 — write 5.
    • Hundreds: after borrowing, 6; 6 − 0 = 6 — write 6.
    • Thousands: 2 is less than 5 — borrow 1 ten thousand: ten thousands 3 → 2; 12 − 5 = 7 — write 7.
    • Ten thousands: after borrowing, 2; 2 is less than 4 — borrow 1 million across the zero: millions 1 → 0, hundred thousands 0 → 9; 12 − 4 = 8 — write 8.
    • Hundred thousands: after borrowing, 9; nothing to subtract — write 9.
    • Millions: after borrowing, 0 — a leading zero is not written.

    1,032,743 − 45,089 = 987,654

    Second check: 1,032,743 − 987,654 = 45,089
