### ELM Objectives

The ELM is a math proficiency exam required for all incoming students to schools in the California State University system. You can learn more about the topics on the ELM here.

The lessons in this chapter covers part of the Algebra portion of the ELM exam. Algebra constitutes about 35% of the entire exam. The lessons in this course are most closely tied to the 'use properties of exponents' objective. Other algebraic objectives covered in this course include:

• Evaluate and interpret algebraic expressions
• Simplify algebraic expressions
• Express relationships among quantities using variables
• Solve problems in context that are modeled by linear equations
• Solve quadratic and rational equations (with both numerical and literal coefficients; real solutions only)
• Solve problems in context that are modeled by quadratic equations
• Solve equations and inequalities involving absolute value (in one variable)
• Find and use slopes and intercepts of lines

Mastering the concepts covered in this chapter will provide you with a solid foundation for the ELM Math.
