What is 700 − 348?

Answer

700 − 348 =
352

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

700 − 348 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: 700 − 348

  • Ones: 0 is less than 8 — borrow 1 hundred across the zero: hundreds 7 → 6, tens 0 → 9; 10 − 8 = 2 — write 2.
  • Tens: after borrowing, 9; 9 − 4 = 5 — write 5.
  • Hundreds: after borrowing, 6; 6 − 3 = 3 — write 3.

700 − 348 = 352

Second check: 700 − 352 = 348
