What is 604 − 136?

Answer

604 − 136 =
468

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 − 136 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.

468

Column by column: 604 − 136

  • 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 − 3 = 6 — write 6.
  • Hundreds: after borrowing, 5; 5 − 1 = 4 — write 4.

604 − 136 = 468

Second check: 604 − 468 = 136
