    What is 388 − 149?

    Answer

    388 − 149 =
    239

    With regrouping: 1 borrow — from the tens

    388 − 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.
    7+10
    3 8(was 8, now 7)8 (was 8, now 18)
    −149
    239

    Column by column: 388 − 149

    • Ones: 8 is less than 9 — borrow 1 ten: tens 8 → 7; 18 − 9 = 9 — write 9.
    • Tens: after borrowing, 7; 7 − 4 = 3 — write 3.
    • Hundreds: 3 − 1 = 2 — write 2.

    388 − 149 = 239

    Second check: 388 − 239 = 149
