Basic algebra for users. When I hear about Matrixes and Vectors I am not scared, but I know that troubles are near, because vector algebra can cause me headache. What I usualy need is a basic cookbook with most basic user recipes, "How to do it," and that is what I want to offer you here.

The most basic space is simple: one origin, one x-axis, y-axis and z-axis. But whenever we place an object in such space, we are not necesarily aware but in that moment we create a new space. File:Example.jpg
