What is 605 − 69?

Answer

605 − 69 =
536

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

605 − 69 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.

536

Column by column: 605 − 69

  • Ones: 5 is less than 9 — borrow 1 hundred across the zero: hundreds 6 → 5, tens 0 → 9; 15 − 9 = 6 — write 6.
  • Tens: after borrowing, 9; 9 − 6 = 3 — write 3.
  • Hundreds: after borrowing, 5; nothing to subtract — write 5.

605 − 69 = 536

Second check: 605 − 536 = 69

605 − 69 = 536

How do you check that 605 − 69 = 536?

Add the difference and the subtrahend: 536 + 69 = 605. Getting the minuend back means the difference is right.

How many times do you borrow in 605 − 69?

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 605 − 69?

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.
