and reconcile three different perspectives (symbolic, graphical, and numerical) into a "connected whole." (G. E. 1)

2. Students will be able to demonstrate their ability to reason quantitatively and symbolically to solve problems. (G. E. 7)

B. Learning Outcomes
Students will be able to:

1. Perform basic operations on polynomials, rational expressions and on square roots.
2. Solve first degree equations and inequalities.
3. Graph linear equations and inequalities in two variables.
