What is 1,008 − 325?

Answer

1,008 − 325 =
683

With regrouping across a zero: 2 borrows — there are no hundreds to borrow from, so 1 thousand becomes 10 hundreds, and 1 hundred goes to the tens

1,008 − 325 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: 1,008 − 325

  • Ones: 8 − 5 = 3 — write 3.
  • Tens: 0 is less than 2 — borrow 1 thousand across the zero: thousands 1 → 0, hundreds 0 → 9; 10 − 2 = 8 — write 8.
  • Hundreds: after borrowing, 9; 9 − 3 = 6 — write 6.
  • Thousands: after borrowing, 0 — a leading zero is not written.

1,008 − 325 = 683

Second check: 1,008 − 683 = 325

How many times do you borrow in 1,008 − 325?

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 1,008 − 325?

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.
