[ILUG] OT: Maths and Matrices

[Frank Murphy (Frankly3D)]

Tried Google. but too many hits
ditto Amazon

(No recommended\required school books)

eg:
http://www.sosmath.com/matrix/inverse/inverse.html
many symbols have not seen before re. maths

Looking for a good book(s),
I can study Matrices at home.

Never did them before in school.
Have 4 weeks to master them.

While I have the soap box:
Linear programming (maths style)
Logic (maths)

All the late teens seem to have studied these for the leaving.
