Before evaluating expressions or solving equations, your goal is to always simplify as much as possible. To do this, you should follow some simple steps, especially where variables are concerned. You should know how to use the Distributive Property as well as the rules for combining variables.

If you have complex expressions or equations, you first look for addition or subtraction inside the parentheses. Then, you can simply follow the rest of the order of operations (PEMDAS, BEDMAS, BODMAS, BIDMAS). Afterwards, you group like terms before combining like terms.

In case you were wondering what like terms and unlike terms are and how to group and combine like and unlike terms when variables are involved, this video will enlighten you. If you had problems with what to combine, always keep in mind, that different variables should be treated like different species in real life. That being said, you will master simplifying variable expressions in no time, promised.

Don't try to sneak past this topic in maths if you have difficulties; simplifying variable expressions is one of the most important issues for all your future math topics and in our video it will be explained step by step to you. Relax, lean back, watch and learn.
