Ok, simply put, i am 21, working in a warehouse that i am not even closely challenged, and i feel as if i am getting dull. As unfortunate as it may be, when in highschool learning was low on my rank of importance, and as you can imagine, i don't feel i learned much... Despite it being one of my favorite subjects. However, i am strong willed, and feel i need to sharpen my dull sword before i break the blade.. so to say. And on to the question.. I wish to buy a book or two that can help me learn. What to learn though? I would Like to learn advanced math, algebra, and the like. In reality, i am sure i would just stare at it and be confused. All that was reachable back when it was fresh, but now after being so careless with my tool i call a brain, a lot of math.. especially written math (for what i did i did lazily in my head, why write it i thought then lol), i am poor at now. However if i buy some beginners math book and blaze through it I'll have wasted 50$ or so. I'm looking for those books that teach you new ways to think. I want to think of math in a new way, learn new tricks for old problems, and just go about everything better... and perhaps quicker. If i buy a good book that is too advanced, i can always go down a step and use the same book later on when i am ready.. but if i buy a book that is too dumbed down.. well i don't have any furniture that needs to be propped up lol. So any suggestions? I hope i am in the right forum in general.. i searched and searched, and found this little gem which seems to be full of life.. i just hope you are all accepting of a newcomer who is willing but uneducated. Oh, and on the purchasing, I'd prefer perhaps Amazon.com or Barns & Noble. Thanks to any replies!
