EQUIVALENT EXPRESSION

Today was spent trying to make sure everyone understands that equivalent expressions do not have to look like each other. (Sometimes they will, but not always). However, they do have to get the same value when we substitute in the same value for a variable. (This is a great lifesaver if a student is unsure if they are equivalent). Also, when they are both simplified they will look the same.
