- Systems of Equations.
This segment covers the solution of systems of pairs of linear equations by both the method of elimination (sometimes called the method of addition or the method of of row reduction for large systems) and the method of substitution. Graphical representations and notations of dependence and of inconsistency of parallel pairs are also covered.
- Word Problems.
This segment covers applications of two equations in two unknowns.
- Introduction to Radicals.
This segment covers principal square root and nth roots in general. Simplifying radical expressions is covered including radicals containing variables.
- Adding and Subtracting Radicals.
This segment covers like radical expressions as well as adding and subtracting radical expressions.
