average formula says that (a+b)/2 is equal to the exact middle point between a and b

i still don't get why is that true

Hello /sci/

Any advice for a guy that badly knows algebra and now he needs to know calculus and everything that is related to signals like complex numbers, exponencials, trignometry, euler form, fourier series, etc...

Any advice like books or websites? Thanks

wtf are you even talking about OP

Hey /sci/ what is your opinion on aptitude tests as a form of entry into university. I am a first year undergrad majoring in applied physics, and got in through an aptitude test. In high school I took only a general math course and so I can't do calc or complex algebra (Currently teaching myself) and I also only did Chemistry and no Physics. Should this be allowed? No matter how good someones aptitude for a subject if they don't have the fundamental knowledge then they can't really compete.
