Quote - ...the approach taken in Linear Algebra books is anything but remedial. Quite the opposite, it assumes you are already facile with Algebra, and then takes it to new levels.

First of all, printed that last post out to read in the bus whilst I go to pick up my car from the servo.

Just wanna explain my confusion. In math terms:
Consider that:
a: I want to learn (this math as it applies to Poser) and
b: I'm 57, a full-time nurse and home-maker so Uni is not an option
c: don't wanna be bugging the heck outa ya Bill - yeah, what you say is gold, but you have your limits too!

What do you suggest as a good approach to getting my head around linear Algebra? or is simple arithmetic going to do 90% of what I need to do?

Thanks, mate....
