Great, this really helps me out. Regressing slightly from that particular curriculum, i just received my first book yesterday An Introduction to Mathematical Reasoning by Peter J. Eccles. I bought it because the author suggests that it is a good gateway to uni mathematics. Already in the first chapter, although i found the reading manageable, i couldn’t complete most of the first chapter exercises without referring to the answers in the back. This was quite frustrating because i’d figure i’d at least be able to get through two or three books without getting stuck to the point where no amount of deliberation would get me through the problems on my own.
Now that you’ve confirmed that this enterprise would likely be much harder than what it looks i don’t feel so bad. I will take your advice and possibly look into taking some mathematics courses. I basically want to get into business later on, like in about five years, for i can’t help but think that it is vital to have more than a generally-deemed-adequate knowledge base in the physical sciences before i'm excessively pressured into caring about real-world trivialities. Preceding the physical sciences, of course, even at an intermediate level would be strong skills in mathematics. I might ultimately just have to bite the bullet, however, and accept that i might not be made for academia to the extent i think important.
Spirits are high though! It looks like you’re very knowledgeable in mathematics. I’ll be careful not to bother you too much, but if i do decide to give it a shot on my own (at least so i can say to myself that i didn’t give up too quickly), then i know there’s always a place to bounce ideas around, even if you wouldn't consider your much appreciated assistance “optimal.”
