- compare problem situations that can be solved with equations to problem situations that can be solved with inequalities;
- compare the solution of an equation to the solution set of an inequality;
- solve equations and inequalities using various methods; and
- articulate why it is necessary to “switch” the inequality symbol when dividing or multiplying by a negative value.
