    What is 342 − 128?

    Answer

    342 − 128 =
    214

    With regrouping: 1 borrow — from the tens

    342 − 128 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
    3 4(was 4, now 3)2 (was 2, now 12)
    −128
    214

    Column by column: 342 − 128

    • Ones: 2 is less than 8 — borrow 1 ten: tens 4 → 3; 12 − 8 = 4 — write 4.
    • Tens: after borrowing, 3; 3 − 2 = 1 — write 1.
    • Hundreds: 3 − 1 = 2 — write 2.

    342 − 128 = 214

    Second check: 342 − 214 = 128
