Math for Machine Learning (2009) [pdf] (umiacs.umd.edu)

nice, but: "probability is currently left off"

This is more of a primer on "the first two years of college mathematics" than a primer for Machine Learning, honestly. Still, not a bad resource.

Is there a version including the figures?

Typo: the second requirement for pseudo-inverses should be Adagger A Adagger = Adagger, not A.

It would really be helpful if such mathematical papers included the pronounciation of those greek (or whatever made-up) letters at least once when they are first used.
