    What is 700 − 83?

    Answer

    700 − 83 =
    617

    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

    700 − 83 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)0 (was 0, now 10)
    −83
    617

    Column by column: 700 − 83

    • Ones: 0 is less than 3 — borrow 1 hundred across the zero: hundreds 7 → 6, tens 0 → 9; 10 − 3 = 7 — write 7.
    • Tens: after borrowing, 9; 9 − 8 = 1 — write 1.
    • Hundreds: after borrowing, 6; nothing to subtract — write 6.

    700 − 83 = 617

    Second check: 700 − 617 = 83

    FAQ

    What is 700 − 83?

    700 − 83 = 617

    How do you check that 700 − 83 = 617?

    Add the difference and the subtrahend: 617 + 83 = 700. Getting the minuend back means the difference is right.

    How many times do you borrow in 700 − 83?

    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 700 − 83?

    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.
