What is 500 − 74?

Answer

500 − 74 =
426

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

500 − 74 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: 500 − 74

  • Ones: 0 is less than 4 — borrow 1 hundred across the zero: hundreds 5 → 4, tens 0 → 9; 10 − 4 = 6 — write 6.
  • Tens: after borrowing, 9; 9 − 7 = 2 — write 2.
  • Hundreds: after borrowing, 4; nothing to subtract — write 4.

500 − 74 = 426

Second check: 500 − 426 = 74

FAQ

What is 500 − 74?

500 − 74 = 426

How do you check that 500 − 74 = 426?

Add the difference and the subtrahend: 426 + 74 = 500. Getting the minuend back means the difference is right.

How many times do you borrow in 500 − 74?

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 500 − 74?

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.
