Column by column: 3,702 − 1,234

  • Ones: 2 is less than 4 — borrow 1 hundred across the zero: hundreds 7 → 6, tens 0 → 9; 12 − 4 = 8 — write 8.
  • Tens: after borrowing, 9; 9 − 3 = 6 — write 6.
  • Hundreds: after borrowing, 6; 6 − 2 = 4 — write 4.
  • Thousands: 3 − 1 = 2 — write 2.

3,702 − 1,234 = 2,468

Second check: 3,702 − 2,468 = 1,234
