Column by column: 51,802 − 6,713

  • Ones: 2 is less than 3 — borrow 1 hundred across the zero: hundreds 8 → 7, tens 0 → 9; 12 − 3 = 9 — write 9.
  • Tens: after borrowing, 9; 9 − 1 = 8 — write 8.
  • Hundreds: after borrowing, 7; 7 − 7 = 0 — write 0.
  • Thousands: 1 is less than 6 — borrow 1 ten thousand: ten thousands 5 → 4; 11 − 6 = 5 — write 5.
  • Ten thousands: after borrowing, 4; nothing to subtract — write 4.

51,802 − 6,713 = 45,089

Second check: 51,802 − 45,089 = 6,713
