Hey all, I'm looking for a nice big book of math problems dealing with different basic subjects like algebra, geometry, trigonometry, linear algebra, logic etc. Basically I'm looking for a book like "Berkeley Problems in Mathematics by Paulo Ney De Souza" but on a highschool to first year undergraduate level. So it should be a book with many problems (900+) but also a book with important ones, wherein you actually come away with a better understanding of say, geometry, if you solved the problems. It doesn't have to be a single book either, I don't mind investing in a series of books. https://www.amazon.com/gp/product/0387952071/ref=pd_ecc_rvi_cart_1/102-1874799-5908959 Any advice is appreciated, thank you. This site is wonderful!
