In [i]GeoGebra Classic[/i], geometry and algebra work side by side:[br][br]Using the provided geometry tools in the [i]Toolbar[/i] you can create geometric constructions in the [img]https://wiki.geogebra.org/uploads/thumb/c/c8/Menu_view_graphics.svg/16px-Menu_view_graphics.svg.png[/img] [i]Graphics View[/i]. At the same time the corresponding coordinates and equations are displayed in the [img]https://wiki.geogebra.org/uploads/thumb/4/40/Menu_view_algebra.svg/16px-Menu_view_algebra.svg.png[/img][i] Algebra View[/i]. [br][br]On the other hand, you can directly enter algebraic input, commands and functions into the [i]Input Bar [/i]by using the keyboard. While the graphical representation of all objects is displayed in the [img]https://wiki.geogebra.org/uploads/thumb/c/c8/Menu_view_graphics.svg/16px-Menu_view_graphics.svg.png[/img][i] Graphics View[/i], their algebraic numeric representation is shown in the [img]https://wiki.geogebra.org/uploads/thumb/4/40/Menu_view_algebra.svg/16px-Menu_view_algebra.svg.png[/img] [i]Algebra View.[/i] 

The user interface of [i]GeoGebra Classic[/i] is flexible and can be adapted to your needs.[br][br][b]Examples[/b][br]If you want to use [i]GeoGebra Classic[/i] in early middle school, you may want to work with a blank sheet in the [img]https://wiki.geogebra.org/uploads/thumb/c/c8/Menu_view_graphics.svg/16px-Menu_view_graphics.svg.png[/img] [i]Graphics View[/i] and use geometry tools. Later on, you may want to introduce the [img]https://wiki.geogebra.org/uploads/thumb/7/7d/Stylingbar_graphicsview_show_or_hide_the_axes.svg/16px-Stylingbar_graphicsview_show_or_hide_the_axes.svg.png[/img] [i]coordinate system[/i] using a [img]https://wiki.geogebra.org/uploads/thumb/f/f1/Stylingbar_graphicsview_show_or_hide_the_grid.svg/16px-Stylingbar_graphicsview_show_or_hide_the_grid.svg.png[/img] [i]grid[/i] (accessible from the [img]https://wiki.geogebra.org/uploads/thumb/d/db/Stylingbar_icon_graphics.svg/16px-Stylingbar_icon_graphics.svg.png[/img] [i]Style Bar[/i]) to facilitate working with integer coordinates. [br][br]In high school, you may want to use algebraic input to guide your students through algebra on into calculus, or use the CAS for symbolic computations.[br][br][i]GeoGebra Classic’s[/i] user interface also provides a variety of dialogs. Different [url=https://wiki.geogebra.org/en/Accessibility]accessibility features[/url] as well as [url=https://wiki.geogebra.org/en/Keyboard_Shortcuts]keyboard shortcuts[/url] allow you to access many features of GeoGebra more conveniently.
