    What is 706 − 187?

    Answer

    706 − 187 =
    519

    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

    706 − 187 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)6 (was 6, now 16)
    −187
    519

    Column by column: 706 − 187

    • Ones: 6 is less than 7 — borrow 1 hundred across the zero: hundreds 7 → 6, tens 0 → 9; 16 − 7 = 9 — write 9.
    • Tens: after borrowing, 9; 9 − 8 = 1 — write 1.
    • Hundreds: after borrowing, 6; 6 − 1 = 5 — write 5.

    706 − 187 = 519

    Second check: 706 − 519 = 187

    FAQ

    What is 706 − 187?

    706 − 187 = 519

    How do you check that 706 − 187 = 519?

    Add the difference and the subtrahend: 519 + 187 = 706. Getting the minuend back means the difference is right.

    How many times do you borrow in 706 − 187?

    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 706 − 187?

    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.
