    What is 903 − 325?

    Answer

    903 − 325 =
    578

    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

    903 − 325 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.
    89+10
    9(was 9, now 8)0(was 0, now 9)3 (was 3, now 13)
    −325
    578

    Column by column: 903 − 325

    • Ones: 3 is less than 5 — borrow 1 hundred across the zero: hundreds 9 → 8, tens 0 → 9; 13 − 5 = 8 — write 8.
    • Tens: after borrowing, 9; 9 − 2 = 7 — write 7.
    • Hundreds: after borrowing, 8; 8 − 3 = 5 — write 5.

    903 − 325 = 578

    Second check: 903 − 578 = 325

    FAQ

    What is 903 − 325?

    903 − 325 = 578

    How do you check that 903 − 325 = 578?

    Add the difference and the subtrahend: 578 + 325 = 903. Getting the minuend back means the difference is right.

    How many times do you borrow in 903 − 325?

    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 903 − 325?

    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.
