Column by column: 111 − 19

  • Ones: 1 is less than 9 — borrow 1 ten: tens 1 → 0; 11 − 9 = 2 — write 2.
  • Tens: after borrowing, 0; 0 is less than 1 — borrow 1 hundred: hundreds 1 → 0; 10 − 1 = 9 — write 9.
  • Hundreds: after borrowing, 0 — a leading zero is not written.

111 − 19 = 92

Second check: 111 − 92 = 19
