    What is 661 − 307?

    Answer

    661 − 307 =
    354

    With regrouping: 1 borrow — from the tens

    661 − 307 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.
    5+10
    6 6(was 6, now 5)1 (was 1, now 11)
    −307
    354

    Column by column: 661 − 307

    • Ones: 1 is less than 7 — borrow 1 ten: tens 6 → 5; 11 − 7 = 4 — write 4.
    • Tens: after borrowing, 5; 5 − 0 = 5 — write 5.
    • Hundreds: 6 − 3 = 3 — write 3.

    661 − 307 = 354

    Second check: 661 − 354 = 307
