Good evening, I have a background on one-variable Calculus and I am currently self-studying Calculus from Leithold's "The Calculus with Analytic Geometry". When I finish the part about infinite series, I plan to start studying Numerical Analysis. I would like to ask what book on Numerical Analysis I should use. Hamming's "Numerical Methods for Scientists and Engineers" seems to be highly regarded, but I don't know what is the necessary mathematical background for reading it. Probability seems to be also necessary for understanding its content. I don't find anywhere in the Internet information about prerequisites for reading this book. My question is, basically: what book could suit my needs? Is there any more mathematics knowledge necessary for studying Numerical Analysis? Thank you in advance.
