05 - Evaluating Algebraic Expressions, Part 1

In this lesson, you will learn what an algebraic expression is and why they are important in algebra. Algebraic expressions are evaluated by substituting the value of the variable in the expression then simplifying the result.

This is used when solving equations, inequalities, radicals, graphing and more. Simplifying algebraic expressions is a core concept in algebra that is used in almost every skill.

Thank you for this. I never paid attention to algebra during high school until later, when it was too late. By that point it was much too intimidating since I couldn't locate where to start. This playlist is helping me lots. I appreciate it.

Don’t know if it’s because I’m 10 years older or I love your teaching but I get this so much easier than I did at school! Watching just for something to listen to at work but enjoying learning so much!

Thank you. I hope you enjoy 2021 because you are amazing at teaching things I don't need to learn now. My teacher did NOT teach this to us at all and expects us to do this without a video or any knowledge of how to do this. So, this really helped thanks.
