One in a series of exercises that demonstrate how to accomplish real-world computing tasks using time- and work-saving techniques.
You and a friend are hanging out at an Internet cafe one afternoon. The two of you are talking about cool computer stuff and your friend tells you he knows a way that he can create a spreadsheet, complete with data and formulas, using Notepad.
You say 'no way', but he insists he can. He jots a few lines down on
a piece of scrap paper and shows it to you. Here's what he wrote:
10
20
30
=sum(a1:a3),Sum
=min(a1:a3),Minimum
=max(a1:a3),Maximum
Are you convinced?
