    What is 850 − 203?

    Answer

    850 − 203 =
    647

    With regrouping: 1 borrow — from the tens

    850 − 203 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.
    4+10
    8 5(was 5, now 4)0 (was 0, now 10)
    −203
    647

    Column by column: 850 − 203

    • Ones: 0 is less than 3 — borrow 1 ten: tens 5 → 4; 10 − 3 = 7 — write 7.
    • Tens: after borrowing, 4; 4 − 0 = 4 — write 4.
    • Hundreds: 8 − 2 = 6 — write 6.

    850 − 203 = 647

    Second check: 850 − 647 = 203
