    What is 200 − 71?

    Answer

    200 − 71 =
    129

    With regrouping across a zero: 2 borrows — there are no tens to borrow from, so 1 hundred becomes 10 tens, and 1 ten goes to the ones

    200 − 71 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.
    19+10
    2(was 2, now 1)0(was 0, now 9)0 (was 0, now 10)
    −71
    129

    Column by column: 200 − 71

    • Ones: 0 is less than 1 — borrow 1 hundred across the zero: hundreds 2 → 1, tens 0 → 9; 10 − 1 = 9 — write 9.
    • Tens: after borrowing, 9; 9 − 7 = 2 — write 2.
    • Hundreds: after borrowing, 1; nothing to subtract — write 1.

    200 − 71 = 129

    Second check: 200 − 129 = 71

    FAQ

    What is 200 − 71?

    200 − 71 = 129

    How do you check that 200 − 71 = 129?

    Add the difference and the subtrahend: 129 + 71 = 200. Getting the minuend back means the difference is right.

    How many times do you borrow in 200 − 71?

    2 borrows: each time the top digit was smaller than the one below it, 1 was borrowed from the column on the left.

    Why does 0 become 9 when borrowing in 200 − 71?

    The zero has nothing to lend, so it first borrows 1 from its left neighbour and becomes 10; then it lends 1 to the column on its right and keeps 9.
