Column by column: 1,037 − 354

  • Ones: 7 − 4 = 3 — write 3.
  • Tens: 3 is less than 5 — borrow 1 thousand across the zero: thousands 1 → 0, hundreds 0 → 9; 13 − 5 = 8 — write 8.
  • Hundreds: after borrowing, 9; 9 − 3 = 6 — write 6.
  • Thousands: after borrowing, 0 — a leading zero is not written.

1,037 − 354 = 683

Second check: 1,037 − 683 = 354
