5. Then you write again five numbers, which is equal to 99999.
6. Finally, add all five numbers, and your answer is the same as what you gave earlier.

1. Your friend wrote:	21596
2. Your friend again writes:	56378
3. Now you write:	43621
4. Your friend again writes:	32580
5. Now you write:	67419
6. Add all 5 numbers:	221594

For answers, just add 2 before the number and subtract 2 from the last digits: 221594.

If the last number is 1, it means 11-2=9. If the last number is 0, it means 10-2=8. Similarly, if the last numbers are 100, it means 100-2=98. For example, if your friend writes the number 21590, that means the answer is 221588. If your friend writes the number 21500, that means the answer is 221498. Similarly, if your friend writes 21591, that means the answer is 221589.

When you write a number, make sure the total sum is 9. If the user writes 5, then you write 4. If the user writes 9, then you write 0. Similarly, 8 means you write 1.
