    What is 604 − 256?

    Answer

    604 − 256 =
    348

    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

    604 − 256 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.
    59+10
    6(was 6, now 5)0(was 0, now 9)4 (was 4, now 14)
    −256
    348

    Column by column: 604 − 256

    • Ones: 4 is less than 6 — borrow 1 hundred across the zero: hundreds 6 → 5, tens 0 → 9; 14 − 6 = 8 — write 8.
    • Tens: after borrowing, 9; 9 − 5 = 4 — write 4.
    • Hundreds: after borrowing, 5; 5 − 2 = 3 — write 3.

    604 − 256 = 348

    Second check: 604 − 348 = 256

    FAQ

    What is 604 − 256?

    604 − 256 = 348

    How do you check that 604 − 256 = 348?

    Add the difference and the subtrahend: 348 + 256 = 604. Getting the minuend back means the difference is right.

    How many times do you borrow in 604 − 256?

    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 604 − 256?

    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.
