Matrices, vectors, vector spaces, transformations. Covers all topics in a first year college linear algebra course. This is an advanced course normally taken by science or engineering majors after taking at least two semesters of calculus (although calculus really isn't a prereq) so don't confuse this with regular high school algebra.Study Online with Cramster Study Groups!

As for my twitter account and the sudden increase of tweets, I think it's due to all the pearls I've already curated, and how I activated the syncronization process of both accounts. Not too sure of that one though. by Jul 8

I noticed that when I started expanding each tree into multiples, and I hit the small black circle above each one. The indication of subjects attracting more trees, from within trees came to my attention, so I began to continue to grow more subjects I already had on my web guide. by Jul 8
I think what happened is, my web guide I built has helped me to expand onto pearl trees in such a way, that it appeals to many topics on pearl. The way pearltrees functions is based on subject content being rendered into each tree, including the titling of the specific tree. by Jul 8
TED is awesome for sharing info about new educational forums & developments, I enjoy learning on the web & also web development which I learned within the last year and a half or so. by Jul 7
