Everything you always wanted to know about mathematics (2013) [pdf]
Does anyone know of an entry level book that could take someone through say, high school math to college alegbra / calculus?This is my singular biggest hurdle in going back to school to finish my degree and I'd love to fill the gaps I have around mathematics so I can not only finish my degree; I'd also like to participate in some more advanced computer science  that rely heavily on underlying computation.
