well, actually, they do reccommend a graphics display calculator for the maths course - but the chemistry people won't let us have CAS ? algebra display ? something like that... because people put whole equations into them apparently... and we are supposed to remember them... and put them on the paper. then sub in the numbers / units. then enter things into our calculator and get the actual proper answer out the other end. and i can't do that last bit. even if the other bits work alright. even if i can get the units out. i can't get the actual number.

and there are brackets and exponents and negative powers and... i don't know what i'm doing wrong except that there is f*ck all relation between how it looks on the page and what i'm supposed to type in and... i'm having enough trouble with learning the equations and putting the numbers into the right places in them... that latter bit... what does it matter? what's it for? what's it testing? why does it matter? i don't understand.
