    What is 430 − 28?

    Answer

    430 − 28 =
    402

    With regrouping: 1 borrow — from the tens

    430 − 28 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.
    2+10
    4 3(was 3, now 2)0 (was 0, now 10)
    −28
    402

    Column by column: 430 − 28

    • Ones: 0 is less than 8 — borrow 1 ten: tens 3 → 2; 10 − 8 = 2 — write 2.
    • Tens: after borrowing, 2; 2 − 2 = 0 — write 0.
    • Hundreds: nothing to subtract — write 4.

    430 − 28 = 402

    Second check: 430 − 402 = 28
