Example-2

Th H T O Ones: 3 Ones – 4 Ones (Not Possible)

3 10 9 13 Borrow: Hundreds Tens Ones
1 borrowed from Hundreds 10 Tens

7 4 0 3 1 borrowed from Tens 13 Ones

Now, 13 Ones – 4 Ones =9 Ones (Write)

- 2 3 9 4 Tens: 10 Tens - 1 borrowed by Ones = 9 left

Now, 9 Tens – 9 Tens = 0 Ten (Write)
= 5 0 0 9 Hundreds: 4 Hundreds – 1 borrowed by Tens=3

left

Now, 3 Hundreds – 3 Hundreds = 0 Hundred
Thus, 7403 – 2394 = 5009 (Write)
