What is 604 − 256?

Answer

604 − 256 =
348

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

604 − 256 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: 604 − 256

  • Ones: 4 is less than 6 — borrow 1 hundred across the zero: hundreds 6 → 5, tens 0 → 9; 14 − 6 = 8 — write 8.
  • Tens: after borrowing, 9; 9 − 5 = 4 — write 4.
  • Hundreds: after borrowing, 5; 5 − 2 = 3 — write 3.

604 − 256 = 348

Second check: 604 − 348 = 256
