    What is 900 − 94?

    Answer

    900 − 94 =
    806

    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

    900 − 94 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.
    89+10
    9(was 9, now 8)0(was 0, now 9)0 (was 0, now 10)
    −94
    806

    Column by column: 900 − 94

    • Ones: 0 is less than 4 — borrow 1 hundred across the zero: hundreds 9 → 8, tens 0 → 9; 10 − 4 = 6 — write 6.
    • Tens: after borrowing, 9; 9 − 9 = 0 — write 0.
    • Hundreds: after borrowing, 8; nothing to subtract — write 8.

    900 − 94 = 806

    Second check: 900 − 806 = 94

    FAQ

    What is 900 − 94?

    900 − 94 = 806

    How do you check that 900 − 94 = 806?

    Add the difference and the subtrahend: 806 + 94 = 900. Getting the minuend back means the difference is right.

    How many times do you borrow in 900 − 94?

    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 900 − 94?

    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.
