Title: excellent detail
Review: this text is very user friendly. the sample problems are completely worked out, so there is no guessing where the solution comes from. it's a great review book, and very easy to understand for a first time learner of linear algebra. although, i did find a few typos and insignificant errors. for example, when asked to find a parametric representation of the line passing through the point p(4,-2,3,1) in the direction of a vector u=[2,5,-7,8] , the equation for x2 is mistyped as x2=-2+2t. (2t where 5t should be)
