What is 600 − 92?

Answer

600 − 92 =
508

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

600 − 92 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: 600 − 92

  • Ones: 0 is less than 2 — borrow 1 hundred across the zero: hundreds 6 → 5, tens 0 → 9; 10 − 2 = 8 — write 8.
  • Tens: after borrowing, 9; 9 − 9 = 0 — write 0.
  • Hundreds: after borrowing, 5; nothing to subtract — write 5.

600 − 92 = 508

Second check: 600 − 508 = 92

FAQ

What is 600 − 92?

600 − 92 = 508

How do you check that 600 − 92 = 508?

Add the difference and the subtrahend: 508 + 92 = 600. Getting the minuend back means the difference is right.

How many times do you borrow in 600 − 92?

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 600 − 92?

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.
