I actually made no mathematical mistakes. You just wanted me to in your pathetic attempt for validation.
This latter is quite likely, as I don’t frequent fast food restaurants, so I would really have no need for your services.
I really do wonder why you have to try to validate yourself so hard. Sadly I don’t care enough about your little tantrum to try and look up where I embarrassed you previously, though I’m sure it would be good for a few laughs.
I’ll be done reading/responding to you now. It’s obvious all you can do is repeat yourself because you have no actual argument. Good luck with that validation you require; you’re not going to get it on these boards. Perhaps you should try talking with your parents when your classes let out for the day.
