    What is 1,011,110 − 23,456?

    Answer

    1,011,110 − 23,456 =
    987,654

    With regrouping across a zero: 6 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

    1,011,110 − 23,456 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: 1,011,110 − 23,456

    • Ones: 0 is less than 6 — borrow 1 ten: tens 1 → 0; 10 − 6 = 4 — write 4.
    • Tens: after borrowing, 0; 0 is less than 5 — borrow 1 hundred: hundreds 1 → 0; 10 − 5 = 5 — write 5.
    • Hundreds: after borrowing, 0; 0 is less than 4 — borrow 1 thousand: thousands 1 → 0; 10 − 4 = 6 — write 6.
    • Thousands: after borrowing, 0; 0 is less than 3 — borrow 1 ten thousand: ten thousands 1 → 0; 10 − 3 = 7 — write 7.
    • Ten thousands: after borrowing, 0; 0 is less than 2 — borrow 1 million across the zero: millions 1 → 0, hundred thousands 0 → 9; 10 − 2 = 8 — write 8.
    • Hundred thousands: after borrowing, 9; nothing to subtract — write 9.
    • Millions: after borrowing, 0 — a leading zero is not written.

    1,011,110 − 23,456 = 987,654

    Second check: 1,011,110 − 987,654 = 23,456
