From Huben's Wiki
Vocabulary:
- absolute value, empty set, intersection, conjunction, union, disjunction
1.4:
- evaluate expressions with absolute values
- solve absolute value equations and check the answers
- identify absolute value equations with the empty set as an answer
- identify extraneous solutions by checking
- write absolute value equations from word problems and solve them
1.5:
- trichotomy property of real numbers
- the six equalities and inequalities
- properties of inequalities: +, -, x, /
- special case when x or / with negative number
- solve inequalities using the properties
- graph inequalities on the number line
- express solution sets of inequalities with set-builder notation

1.6
- compound inequalities
- and inequalities are conjunctions, their solutions are intersections (overlaps)
- or inequalities are disjunctions, their solutions are unions
- solve 'and', 'or' compound inequalities and absolute value inequalities
- graph solution sets on number lines
- express solution sets with set-builder notation
- write absolute value inequalities from word problems and solve them
