    What is 112 − 45?

    Answer

    112 − 45 =
    67

    With regrouping: 2 borrows — from the tens and the hundreds

    112 − 45 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.
    010+10
    1(was 1, now 0)1(was 1, now 10)2 (was 2, now 12)
    −45
    67

    Column by column: 112 − 45

    • Ones: 2 is less than 5 — borrow 1 ten: tens 1 → 0; 12 − 5 = 7 — write 7.
    • Tens: after borrowing, 0; 0 is less than 4 — borrow 1 hundred: hundreds 1 → 0; 10 − 4 = 6 — write 6.
    • Hundreds: after borrowing, 0 — a leading zero is not written.

    112 − 45 = 67

    Second check: 112 − 67 = 45
