In this article, we will explore what algebraic expressions are, what they are used for and how they are used in the real world. Algebraic expressions appear in the transition from primary to secondary school or in middle school, around the age of 12. And once they appear, they are here to stay.
In maths, an expression is a combination of numbers, variables, functions (such as addition, subtraction, multiplication or division etc.). Expressions can be thought of as similar to phrases. In language, a phrase on its own may include an action, but it doesn't make a complete sentence.
