Solving Equations Using Addition and Subtraction

Topics for Today:

We began our journey into solving algebraic equations today.  We also discussed what inverse operations are in the context of solving equations.  Students are reminded that all they are accountable for all the mathematics that came before this class, as well as any new learned material.  Mathematics is a cumulative subject, and the skills built in the past will continue to be used to solve new problems.  That means we will continue to integrate fraction and decimal operations into our problem solving.  Equation operations will include all types of real numbers.

Vocabulary:

addition property of equality, subtraction property of equality, inverse operations
