Column by column: 1,070 − 468

  • Ones: 0 is less than 8 — borrow 1 ten: tens 7 → 6; 10 − 8 = 2 — write 2.
  • Tens: after borrowing, 6; 6 − 6 = 0 — write 0.
  • Hundreds: 0 is less than 4 — borrow 1 thousand: thousands 1 → 0; 10 − 4 = 6 — write 6.
  • Thousands: after borrowing, 0 — a leading zero is not written.

1,070 − 468 = 602

Second check: 1,070 − 602 = 468
