    What is 100 − 41?

    Answer

    100 − 41 =
    59

    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

    100 − 41 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.
    09+10
    1(was 1, now 0)0(was 0, now 9)0 (was 0, now 10)
    −41
    59

    Column by column: 100 − 41

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

    100 − 41 = 59

    Second check: 100 − 59 = 41

    FAQ

    What is 100 − 41?

    100 − 41 = 59

    How do you check that 100 − 41 = 59?

    Add the difference and the subtrahend: 59 + 41 = 100. Getting the minuend back means the difference is right.

    How many times do you borrow in 100 − 41?

    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 100 − 41?

    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.
