    What is 242 − 39?

    Answer

    242 − 39 =
    203

    With regrouping: 1 borrow — from the tens

    242 − 39 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.
    3+10
    2 4(was 4, now 3)2 (was 2, now 12)
    −39
    203

    Column by column: 242 − 39

    • Ones: 2 is less than 9 — borrow 1 ten: tens 4 → 3; 12 − 9 = 3 — write 3.
    • Tens: after borrowing, 3; 3 − 3 = 0 — write 0.
    • Hundreds: nothing to subtract — write 2.

    242 − 39 = 203

    Second check: 242 − 203 = 39
