When creating spreadsheets or statistical papers.
Microsoft Word is a word processor. Microsoft Excel is a spreadsheet application.
Microsoft Word is used for writing papers, and Microsoft Excel is for spreadsheets.
Microsoft Word would be for creating word processing documents and Microsoft Excel would be used to create spreadsheets.
Excel and Microsoft word are two different programs. To ask how to you use excel for typing ms word does not make sense
Yes
You would use Microsoft Word for mail merging.
Microsoft Word and Microsoft Excel documents can be linked to each other, so that changes in one document will show up in the other. So it is possible to enter data in Microsoft Word and have it appear in Microsoft Excel. It is also possible to do formulas in tables in Microsoft Word, without linking to Microsoft Excel.
The closest equivalent would be Pages, although it doesn't have quite as many features as Microsoft Word.
If you open it up and go to the help features you would have a hard time not understanding how to use it within 30 minutes. It really straight forward to do basic things. But like anything the more complex the usage the more complex the knowledge required to use it in that fashion. Overall It is fairly simple. --edit I suppose that is assuming you have basic computer skills and are at least some what experienced in the usage of a computer and menus, biased on the ability to post this question it was assumed.
Microsoft access+Microsoft word+Microsoft excel
Microsoft Office
My opinon is Microsoft Word because that's what fits my needs. I have to type a lot so that works for me. My dad has to make graphs a lot for work so he would take excel. And if you need to make brochures or flyers often for buissnesses, then pagemaker is the way to go. but it all depends which one would best suit your needs. Good Luck and choose wisely!
