Use the ee.*Object*.*Method* notation in the Code Editor, such as: 

`ee.Image.add`

## Methods

**Methods** are how users interact with the datasets (**Objects**).  Each Object has it's own set of Methods, and all can be read up on and accessed from the API Reference Guide, or from the Code Editor Docs tab.
