Third software we talk about in class was Microsoft Excel is a spreadsheet program which allows one to enter numerical values or data into the rows or columns of a spreadsheet, and to use these numerical entries for such things as calculations, graphs, and statistical analysis.
An Excel document is called a Workbook. A workbook always has at least one Worksheet. Worksheets are the grid where you can store and calculate data. You can have many worksheets stored inside a workbook, each with a unique worksheet name.
You can create simple and complex formulas in Excel to calculate just about anything. Inputs to a formula may be other cells, the results of other formulas, or just straight-forward math (5*2+3).
The latest version of Microsoft Excel saves documents with the .xlsx extension by default.
I have to say that while I still have not mastered Excel yet, I am very glad we covered it in class. It is so useful for so many different reasons and subjects.
