    What is 64 − 28?

    Answer

    64 − 28 =
    36

    With regrouping: 1 borrow — from the tens

    64 − 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.
    5+10
    6(was 6, now 5)4 (was 4, now 14)
    −28
    36

    Column by column: 64 − 28

    • Ones: 4 is less than 8 — borrow 1 ten: tens 6 → 5; 14 − 8 = 6 — write 6.
    • Tens: after borrowing, 5; 5 − 2 = 3 — write 3.

    64 − 28 = 36

    Second check: 64 − 36 = 28
