Who the **** you think you are that someone from mcdonalds can't be smart? A lot of people work at chain restarunts to pay for school, medical bills, etc.

so does that mean coz they work at macdonalds they cant add up! What a joke and a snobbish thing to say!

everyone who does advanced maths fails at the simple stuff when i did a-level maths i forgot how to do some of the simple stuff, but i was never that great anyway and more importantly, the McDonald's employee had a machine telling them the answer

I work at McDonald's and I am a 5th year senior in college. one of my coworkers is an engineering major taking Engineering Calculus 3 and when I look at him catching up on homework for it when we are slow, it looks nothing like the math I know (Agriculture major with a Business minor here), so, don't feel like that is a FML moment.

haha I just did an exam that included finding derivatives of inverses of logarithms :D it's actually pretty easy >.> but lol that's not FML - you stuffed up. So does everybody once in a while. Deal with it XD

Little bit too much information, since derivatives are pretty easy, and don't have much to do with basic arithmetic.

dont be so snobby about mcdonalds employees, maybe theyre studying maths too just in maccy dees to make their way

everyone makes mistakes. I make that mistake too. but in also in 8 grade. regular math, not algebra. but hey, my math teacher makes mistakes too! don't feel too bad. at least you didn't get cut from a lollipop. break a lollipop, it bites you as its last will and testament.

Mc Donalds employees are most of the time students trying to earn some money. But the deriverate of an invest logarithm... I kind of learned that in highschool. So no big deal, it's not rocket science. I am not voting on this one because abstract calcul and advanced calcul is not the same as simple calcul (i have trouble adding pourcentages to get it to 100%.. i might say that 77% and 33% make 100, which is false).

All this proves is that right now, for you, knowing how to calculate the derivative of *anything* has no bearing at all on what a douche you are. I take that back - it seems to have expedited the process..
