Is this a question of arithmetic, semantics, or just aCustomer
Expert:  Christopher Valk replied 11 years ago.

P1 owes $90, P1 pays $70 so he still owes $20, he took out another loan for $80 so now he owes $100, but then he pays $100, whats does that equal?


His debt is $0.

If you think about the fact that he is "GIVING" money, he would either owe $170 or $90 but if the money he is giving goes towards his loan he would owe $0.
Expert:  Christopher Valk replied 11 years ago.
My final answer is: P1 owes $90
Customer: replied 11 years ago.
Reply to xarqi's Post: It's a financial question. Seeing how after P.1 owed P.2. $90. paid $70. Then, later asked P.2. to give back what was paid earlier so debt of $90. could be paid with a $100. bill. So, P.2 handed P.1. $80. & took the $100. bill. My thought is that P.2. gave $10. more than necessary. Am I right?
Expert:  Christopher Valk replied 11 years ago.

Here are the numbers you gave me:


90-70= 20 | 20+80=100 | 100-100= 0


So how can you come to the conclusion that Person one gave $10 more when the numbers don't say so? Or did you give me the wrong numbers?

Expert:  xarqi replied 11 years ago.
No,Customer that is not right. As at least 4 people have tried
to tell you now, the balance is zero.
Expert:  K McMillion replied 11 years ago.
if this is going by semantics then the answer would be $90 otherwise it would be 0 - I agree with the other posts

Or may be there is an interest that we are not aware of....hmm....
