The site has algebra topics taught with interactive web technologies on how to find the slope of a line from its equation and how to solve 3 equations in 3 unknowns on a spreadsheet, two tutorials on completing the square, quadratic formula - derivation and a tutorial on vertex of a quadratic function.
This paper contains a tutorial introduction to the ideas of geometric algebra, concentrating on its physical applications showing how the definition of a `geometric product of vectors in 2- and 3-dimensional space provides precise geometrical interpretations of the imaginary numbers often used in conventional methods, also has information on bilinear spinor transformations, Hestenes spacetime algebra, mathematical physics, analytic and monogenic functions.
