The algebraic representation of all created objects (i.e. coordinates, equations) are listed 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] in the order of their creation. [br][u]Note[/u]: You can scroll up and down by tapping the background of 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] and moving your finger up and down. 

You can enter Algebraic Input or Commands directly 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]. Tapping the[i] Algebra Input[/i] automatically opens a[i] Virtual Keyboard[/i], which consists of four panels containing[br][list][*]the letters of the Latin alphabet[/*][*]the letters of the Greek alphabet[/*][*]numbers[/*][*]the most used mathematical operators[/*][/list][u]Note[/u]: You may switch between the different panels by tapping the corresponding keys in the lower left corner of the [i]Virtual Keyboard[/i].[br][br]The provided equation editor makes it very easy to enter complex mathematical expressions without losing track of what you are typing.

You may close the [i]Virtual Keyboard[/i] at any time by tapping anywhere 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] or [img]https://wiki.geogebra.org/uploads/thumb/b/bb/Perspectives_algebra_3Dgraphics.svg/20px-Perspectives_algebra_3Dgraphics.svg.png[/img] [i]3D Graphics View[/i].[br][br][u]Hint[/u]: By tapping on the [img]https://wiki.geogebra.org/uploads/thumb/e/eb/Menu-help.svg/20px-Menu-help.svg.png[/img] button, the InputHelp opens, where you can find all commands. If you start entering the first letters of a command, the InputHelp provides all commands, starting with this letters.
