[James Crook]

Thanks Jonathan - you're probably not the last one to report back.

Shri, how are we doing - who has still to report on this?

Jonathan,

If this is correct and you are happy Nicole knows the requested techniques for matrices, please tell Shri so he can tick the box and we can get this group task completed.

Shri, how about an update to the list.  Who are we waiting for?

I've put a page on the wiki on matrix multiplication that may be helpful to the group.

I'm thinking that matrices are not taught well in the States at high school level.  We're going to have to find a way to fix this.  Matrices are a vital mathematical tool used in mathematics, engineering and computing.  Once you get used to what they can do you wouldn't want to do without them.

Sounds good.  What did you get for your answer to exercise 1?  (use your user page on the wiki)

I was actually asking about Task 2.  http://onlinemathcircle.com/wiki/index.php?title=L2_Task_2

Have we got responses from everyone?
