The career and field of study I am choosing is not related to maths much.But I am still interested and I love maths.But I just know math up to highschool level.So I wish to learn more,say as a hobby or skill.
Thus what books can anyone recommend or online resources or even what branch of mathematics to learn .
Edit:I know there are some answers pertaining to this but they dont seem like what I wanted to ask.
Khan academy might be a good starting point.
On youtube you can watch hundreds of their short videos on subjects like algebra, calculus, probability, linear algebra etc.
When you feel like you master that material you can move on to MIT OpenCourseWare on youtube.
Gilbert Strang's Linear algebra.
David Jerison's Single variable calculus.
Denis Auroux's Multivariable calculus.
Tom Leighton's Mathematics for Computer Science.
They also have courses on probability, statistics, differential equations etc.
Other personal favourites, which i actually liked more than MIT, are these
Discrete Mathematics. Arsdigita University. Instructor: Shai Simonson
The Fourier Transforms and its Applications. Standford. Professor Brad Osgood
Probability. Harvard
Probability Primer. Mathematicalmonk's channel
General topology from the very basics, including set theory, techniques for proofs
Graph theory by Sarada Herke
