Mathematics 23 or Mathematics 25 with a minimum grade of C in prerequisite, or qualification by testing (El Camino College Mathematics Placement Test) and assessment.
This is the first in the two-course Extended Elementary Algebra sequence, which begins at a slower pace than elementary algebra. Students examine the connections between the order of operations on real numbers and the elementary algebraic ideas of variables, expressions and equations. Students explore the four fundamental representations of relations between two variables: verbal, algebraic, graphical and numerical. Linear relations serve as the primary example, but students also study quadratic relations. Students are expected to master basic numeric and algebraic manipulation skills, including combining like terms, expanding products and elementary factoring.
Use the properties of operations on the real numbers, including the order of operations, to evaluate, simplify and factor algebraic expressions.
Solve linear equations and inequalities.
Solve quadratic equations by factoring.
Set up and solve application problems using linear equations and inequalities.
Graph linear equations by plotting points or using intercepts and the slope.
Starting with a linear model in tabular, graphical or symbolic form, translate the model into the other forms.
