Section 2: Equations and Inequalities ! A number sentence is an example of an algebraic equation. An algebraic equation is a statement of equality between two _____. Algebraic equations can be number sentences (when both expressions contain only numbers), but often they contain _____ whose values have not been determined.
condition in a real-world or mathematical problem. They compare inequalities to equations and realize that while equations and inequalities are solved using a similar process, inequalities have infinitely many solutions. Students learn to represent these solutions to inequalities on number line diagrams.
