Systems of Linear Equations and Matrices

Abstract

In the introductory chapter we warmed up the engines by studying the equation ax = b. What will we do to follow up on that? I will tell you right away that in this chapter we will deal with transportation problems and chemical reactions, diet manipulations, totocalcio tickets, architectural constructions and meteorology. How is that possible? Am I changing the scope of the book? On the contrary. The fascination of even not very sophisticated mathematics lies precisely in its ability to bring together topics which, at the outset, seem very different.
