    What is 602 − 149?

    Answer

    602 − 149 =
    453

    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

    602 − 149 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.
    59+10
    6(was 6, now 5)0(was 0, now 9)2 (was 2, now 12)
    −149
    453

    Column by column: 602 − 149

    • Ones: 2 is less than 9 — borrow 1 hundred across the zero: hundreds 6 → 5, tens 0 → 9; 12 − 9 = 3 — write 3.
    • Tens: after borrowing, 9; 9 − 4 = 5 — write 5.
    • Hundreds: after borrowing, 5; 5 − 1 = 4 — write 4.

    602 − 149 = 453

    Second check: 602 − 453 = 149

    FAQ

    What is 602 − 149?

    602 − 149 = 453

    How do you check that 602 − 149 = 453?

    Add the difference and the subtrahend: 453 + 149 = 602. Getting the minuend back means the difference is right.

    How many times do you borrow in 602 − 149?

    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 602 − 149?

    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.
