Read "Linear Algebra Demystified - Edition 3 by David McMahon"

Read this book recently, to refresh the dive into improving quantitative analaytical skills.  After a sabbatical for over a decade,  this was a refreshing excercise. Few weeks back, I'd decided  to started with whatever I could lay my hands on first,  found this from local library and completed this as a week long project. In this book the examples are laid out very well  and I got to learn some new concepts as well. Will solve the complete question bank when i get time in future.
