I'm glad you asked that question.
I'm taking algebra, for my second year (since our state raised the requirements, now everyone has to get knocked down and start way back in algebra), and i don't like it. lol.
The basics is the only really thing IMO that we should really care about, that's really the only thing we will care to use!
Like, I don't know WHO is going to use the quadratic formula in REAL life, except for someone with a job like that.
Sometimes it gets irritating.
Same thing with physics,
i dont know ANYONE who calculates the IMA (Ideal Mechanical Advantage) of ANYTHING. Maybe some people do, but i'm going to go out on a limb, and say most people DONT. It seems like they (education system) tries to shove so much crap down our throat before we're outta there, it goes so fast we don't even remember or understand most of it.
But to answer your question, i'm going to go with goobimama and say no, excluding school.
