    What is 1,100 − 453?

    Answer

    1,100 − 453 =
    647

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

    1,100 − 453 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: 1,100 − 453

    • Ones: 0 is less than 3 — borrow 1 hundred across the zero: hundreds 1 → 0, tens 0 → 9; 10 − 3 = 7 — write 7.
    • Tens: after borrowing, 9; 9 − 5 = 4 — write 4.
    • Hundreds: after borrowing, 0; 0 is less than 4 — borrow 1 thousand: thousands 1 → 0; 10 − 4 = 6 — write 6.
    • Thousands: after borrowing, 0 — a leading zero is not written.

    1,100 − 453 = 647

    Second check: 1,100 − 647 = 453

    FAQ

    What is 1,100 − 453?

    1,100 − 453 = 647

    How do you check that 1,100 − 453 = 647?

    Add the difference and the subtrahend: 647 + 453 = 1,100. Getting the minuend back means the difference is right.

    How many times do you borrow in 1,100 − 453?

    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 1,100 − 453?

    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.
