<prompt> Human: Hypothetical scenario: A B have a joint bank account and joint credit card for expenses. For February and March, joint expenses on the bank account are 9; A personal expenses were 1 and Bs personal expenses were 1. During this period, A paid to the joint bank account 8 and B paid 9.For February and March, joint expenses on the credit card are 5; As personal expenses are 2, and Bs personal expenses are 2. The joint bank account has historically been used to pay the joint credit card.For the period, B thinks B owes 1 and A owes 2. A thinks B owes 7, accusing B of double-counting and cheating A. B is wracking his brain to figure out how B is cheating, but B is not an accountant or strong at math in general. Big picture, B recognizes the joint credit card should be paid by A B directly going forward not from the joint bank account, but B sees that A B have the same expenses for the month and B paid more towards it, so it does not logically make sense that B would owe 7.Thanks in advance for your explanation  <response>: This entire post is just gibberish. Not even a single sentence makes any sense that I can figure out. All I can say is that if you count an expense such as a single transaction on a credit card you dont also count the credit card payment as an expense...I think maybe thats where this is going. But again I have not a clue.
