    What is 500 − 39?

    Answer

    500 − 39 =
    461

    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

    500 − 39 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.
    49+10
    5(was 5, now 4)0(was 0, now 9)0 (was 0, now 10)
    −39
    461

    Column by column: 500 − 39

    • Ones: 0 is less than 9 — borrow 1 hundred across the zero: hundreds 5 → 4, tens 0 → 9; 10 − 9 = 1 — write 1.
    • Tens: after borrowing, 9; 9 − 3 = 6 — write 6.
    • Hundreds: after borrowing, 4; nothing to subtract — write 4.

    500 − 39 = 461

    Second check: 500 − 461 = 39

    FAQ

    What is 500 − 39?

    500 − 39 = 461

    How do you check that 500 − 39 = 461?

    Add the difference and the subtrahend: 461 + 39 = 500. Getting the minuend back means the difference is right.

    How many times do you borrow in 500 − 39?

    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 500 − 39?

    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.
