    What is 123 − 47?

    Answer

    123 − 47 =
    76

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

    123 − 47 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.

    −47
    76

    Column by column: 123 − 47

    • Ones: 3 is less than 7 — borrow 1 ten: tens 2 → 1; 13 − 7 = 6 — write 6.
    • Tens: after borrowing, 1; 1 is less than 4 — borrow 1 hundred: hundreds 1 → 0; 11 − 4 = 7 — write 7.
    • Hundreds: after borrowing, 0 — a leading zero is not written.

    123 − 47 = 76

    Second check: 123 − 76 = 47
