What is 1,202 − 519?

Answer

1,202 − 519 =
683

With regrouping across a zero: 3 borrows — there are no tens to borrow from, so 1 hundred becomes 10 tens, and 1 ten goes to the ones

1,202 − 519 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: 1,202 − 519

  • Ones: 2 is less than 9 — borrow 1 hundred across the zero: hundreds 2 → 1, tens 0 → 9; 12 − 9 = 3 — write 3.
  • Tens: after borrowing, 9; 9 − 1 = 8 — write 8.
  • Hundreds: after borrowing, 1; 1 is less than 5 — borrow 1 thousand: thousands 1 → 0; 11 − 5 = 6 — write 6.
  • Thousands: after borrowing, 0 — a leading zero is not written.

1,202 − 519 = 683

Second check: 1,202 − 683 = 519

How many times do you borrow in 1,202 − 519?

3 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 1,202 − 519?

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.
