    What is 1,031 − 348?

    Answer

    1,031 − 348 =
    683

    With regrouping across a zero: 3 borrows — there are no hundreds to borrow from, so 1 thousand becomes 10 hundreds, and 1 hundred goes to the tens

    1,031 − 348 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.

    Column by column: 1,031 − 348

    • Ones: 1 is less than 8 — borrow 1 ten: tens 3 → 2; 11 − 8 = 3 — write 3.
    • Tens: after borrowing, 2; 2 is less than 4 — borrow 1 thousand across the zero: thousands 1 → 0, hundreds 0 → 9; 12 − 4 = 8 — write 8.
    • Hundreds: after borrowing, 9; 9 − 3 = 6 — write 6.
    • Thousands: after borrowing, 0 — a leading zero is not written.

    1,031 − 348 = 683

    Second check: 1,031 − 683 = 348

    FAQ

    What is 1,031 − 348?

    1,031 − 348 = 683

    How do you check that 1,031 − 348 = 683?

    Add the difference and the subtrahend: 683 + 348 = 1,031. Getting the minuend back means the difference is right.

    How many times do you borrow in 1,031 − 348?

    3 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 1,031 − 348?

    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.
