##### MEDIUM SIMPLIFYING EXPRESSIONS

### Course Overview

An expression is a grouping that can include any combination of numbers, symbols, and operators (addition, subtraction, multiplication, division). The one thing that expressions don’t have are equal signs. The presence of an equal sign makes an equation, not an expression, although an expression can be part of an equation. Since the expressions we’ll be dealing with are algebraic we know that they will include algebraic variables, making them a tad bit more abstract. You’ll often be asked to “simplify algebraic expressions”, that means you want to rewrite the expression as shortly as possible, so combine all the things you can!
