What is 301 − 98?

Answer

301 − 98 =
203

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

301 − 98 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: 301 − 98

  • Ones: 1 is less than 8 — borrow 1 hundred across the zero: hundreds 3 → 2, tens 0 → 9; 11 − 8 = 3 — write 3.
  • Tens: after borrowing, 9; 9 − 9 = 0 — write 0.
  • Hundreds: after borrowing, 2; nothing to subtract — write 2.

301 − 98 = 203

Second check: 301 − 203 = 98

2 borrows: each time the top digit was smaller than the one below it, 1 was borrowed from the column on the left.
