Start subtracting from one’s place. We can not subtract 6 from 4 so borrow it from tens digit and the tens digit is decreased by 1. Now 14-6=8.Write 8 under units place. We can not subtract 3 from 2 so borrow it from hundreds digit and hundreds digit is decreased by 1.Now 12-3=9. Write 9 under tens place. After borrowing from thousand’s place subtract 2 from 10 and write the digit 8 under hundreds place. Subtract 1 from 8 and write the result under thousands place.
