Book Recommendations for Maths

[Skrew]

Hello.

I would like recommendations for a couple books.

One which covers introductory number theory, algebra - etc(these looked interesting, I'm not sure which would be best but the "fundamental concepts of algebra" looked pretty good on goggle books -

One which gives a fairly indepth look at both trig and geometry

And a good linear algebra book.(I looked at these, I'm not sure which would be best -

I have taken calc 1-3 and done some differential equation stuff but, it feels like I could benefit greatly from looking at these subjects, I feel it would solidify my understanding verses just plugging numbers into equations and following instructions on how to solve them.

Dover books are preferable due to their greatly reduced price.

I can't say much about the linear algebra books, but if you're looking to enter modern algebra, that second book you posted (the green one) is hard to follow (not good as an introductory book). For modern algebra, I can recommend you: "Modern Algebra An Introduction" by John R. Durbin (Fifth Edition) - https://www.amazon.com/dp/0471433357/?tag=pfamazon01-20
