M icrosoft Excel is a spreadsheet pacakge. In its simplest form, a spreadsheet consists of a grid into which you can enter numbers, text and formulae so that you can perform calculations quickly and easily. The rows and columns of the grid can be linked to each other so that when you make a change in one part of the grid any linked calculations in another part of the grid will be recalculated automatically. For example, the effect which a change in the VAT rules would have on student living standards could be determined quickly and easily.
E xcel also provides a wide range of graphical tools.
Charts can also help you evaluate your data and make comparisons between different worksheet values. Graphic objects such as lines, arrows and added text can be placed on worksheets and charts to draw attention to specific points. In addition you can use the drawing tools to produce flow charts, ground plans and other graphical material for insertion into essays and reports.
