=**Vocabulary**= Words you should already know (link to a document to revise - matching words with definitions/expressions)

- **algebraic expression → an expression formed from letters, symbols and numbers ** - **formula → has a solution dependent upon variables that are known (e.g. V=IR, scientists love these) ** - **function → for any chosen value of x, the related value for y can be calculated (e.g. y = 3x - 4) **

Vocab and terminology is so important as we need to know what is the question asking for? - What not to do! =Symbols= Familiarise yourself with these symbols as these are going to help you manipulate equations and get the answers you've been searching for!
