    What is 707 − 239?

    Answer

    707 − 239 =
    468

    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

    707 − 239 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.
    69+10
    7(was 7, now 6)0(was 0, now 9)7 (was 7, now 17)
    −239
    468

    Column by column: 707 − 239

    • Ones: 7 is less than 9 — borrow 1 hundred across the zero: hundreds 7 → 6, tens 0 → 9; 17 − 9 = 8 — write 8.
    • Tens: after borrowing, 9; 9 − 3 = 6 — write 6.
    • Hundreds: after borrowing, 6; 6 − 2 = 4 — write 4.

    707 − 239 = 468

    Second check: 707 − 468 = 239

    FAQ

    What is 707 − 239?

    707 − 239 = 468

    How do you check that 707 − 239 = 468?

    Add the difference and the subtrahend: 468 + 239 = 707. Getting the minuend back means the difference is right.

    How many times do you borrow in 707 − 239?

    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 707 − 239?

    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.
