Expressions versus Equations. A difference between expressions and equations is what each represents. An expression shows a math relationship. One key to an expression is that there is no solution. An expression does not have an answer. An expression, however, can be evaluated. To evaluate an expression, substitute values for the variables.
What's the difference between an expression and an equation? Alrighty folks, I have a simple question for the fans of critical thinking and/or you (fellow) math heads: In your own words what do you think is the difference between a mathematical expression and an equation. Secondly under what conditions would they be the same. No cheating.
