Open Office is a suite of office tools for word processing, spreadsheets, presentations, graphics, databases and maths formulas.

It is easy to learn and is very similar to other office software in look and feel and in features. The Open Office website contains tutorials and manuals.

The word processor, Writer, is suitable for making professional documents, reports, newsletters and brochures.

A powerful spreadsheet called Calc contains complex tools for calculation, data analysis and visualisation; its built-in charting tools are able to make customisable 2D and 3D charts.

The presentation utility, Impress, uses effects, animation and drawing tools to help you create great multimedia slide shows to present the way you want to.

Use the Draw component to produce either simple diagrams or complex 3D pictures and special effects for use in documents and presentations.

The database tool, Base, gives you all the tools you need for day to day database work in a simple spreadsheet-like form.

Math is a straightforward editor for maths formulas and equations.
