As someone who has zero calc training nor linear algebra (some discrete mathematics was all I took in University), what are some recommended start point to most quickly be up to speed to digest the resources posted both in the OP and by other commenters in this thread? Just a bit of background about where I am at math-wise: I tried taking Andrew Ng's ML course, and quickly fell behind starting with the second programming assignment (it was implementing a linear regression algo, I believe).
