    What is 1,074 − 427?

    Answer

    1,074 − 427 =
    647

    With regrouping: 2 borrows — from the tens and the thousands

    1,074 − 427 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.
    0+106+10
    1(was 1, now 0)0 (was 0, now 10)7(was 7, now 6)4 (was 4, now 14)
    −427
    647

    Column by column: 1,074 − 427

    • Ones: 4 is less than 7 — borrow 1 ten: tens 7 → 6; 14 − 7 = 7 — write 7.
    • Tens: after borrowing, 6; 6 − 2 = 4 — write 4.
    • Hundreds: 0 is less than 4 — borrow 1 thousand: thousands 1 → 0; 10 − 4 = 6 — write 6.
    • Thousands: after borrowing, 0 — a leading zero is not written.

    1,074 − 427 = 647

    Second check: 1,074 − 647 = 427
