    What is 103 − 36?

    Answer

    103 − 36 =
    67

    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

    103 − 36 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)3 (was 3, now 13)
    −36
    67

    Column by column: 103 − 36

    • Ones: 3 is less than 6 — borrow 1 hundred across the zero: hundreds 1 → 0, tens 0 → 9; 13 − 6 = 7 — write 7.
    • Tens: after borrowing, 9; 9 − 3 = 6 — write 6.
    • Hundreds: after borrowing, 0 — a leading zero is not written.

    103 − 36 = 67

    Second check: 103 − 67 = 36

    FAQ

    What is 103 − 36?

    103 − 36 = 67

    How do you check that 103 − 36 = 67?

    Add the difference and the subtrahend: 67 + 36 = 103. Getting the minuend back means the difference is right.

    How many times do you borrow in 103 − 36?

    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 103 − 36?

    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.
