# When You Start &appname;

When you start &app;, the following window is displayed.

## &app; Window

Shows &app; main window. Contains titlebar, menubar, toolbar and working area. Menubar contains File, Edit, Calculator, Settings, and Help menus.

The &app; window contains the following elements:

Menubar.

  The menus on the menubar contain all of the commands that you need to work with files in &app;.

Toolbar.

  The toolbar contains a subset of the commands that you can access from the menubar.

Working area

  The working area is the primary method of interacting with the application.

  The working area initially has just the Console tab which is the main way of interacting with the calculator. Here you type expressions and the results are immediately returned after you hit the Enter key.

  Alternatively you can write longer programs and those can appear in separate tabs and can be stored in files for later retrieval.
