# If I want to learn about tensor mathematics - where do I need to start

If I want to learn about tensor mathematics - where do I need to start (i.e. what precursory mathematical knowledge will I need) and does anyone have any good site/book recommendations?

thanks

This is what I often recommend --

If you don't already have any, then you'll need to have some background in linear algebra (and for starting tensors, you'll also need familiarity with calculus in Rn space (multivariable calculus)). This book covers the multivariable calculus, but you'll need to learn linear algebra from some other source.
