    What is 551 − 149?

    Answer

    551 − 149 =
    402

    With regrouping: 1 borrow — from the tens

    551 − 149 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.
    4+10
    5 5(was 5, now 4)1 (was 1, now 11)
    −149
    402

    Column by column: 551 − 149

    • Ones: 1 is less than 9 — borrow 1 ten: tens 5 → 4; 11 − 9 = 2 — write 2.
    • Tens: after borrowing, 4; 4 − 4 = 0 — write 0.
    • Hundreds: 5 − 1 = 4 — write 4.

    551 − 149 = 402

    Second check: 551 − 402 = 149
