Welcome! Hello, and Wikipedia:Welcome, newcomers to Wikipedia. Thank you for your contributions. I hope you like the place and decide to stay. Here are a few good links for newcomers: *Wikipedia:How to edit a page *Wikipedia:Tutorial *Wikipedia:Picture tutorial *Wikipedia:How to write a great article *Wikipedia:Naming conventions *Wikipedia:Manual of Style *If you're ready for the complete list of Wikipedia documentation, there's also Wikipedia:Topical index. I hope you enjoy editing here and being a Wikipedia:Wikipedians! By the way, you can sign your name on Talk and vote pages using three tildes, like this: ~~~. Four tildes (~~~~) produces your name and the current date. If you have any questions, see the Wikipedia:Help, add a question to the Wikipedia:village pump or ask me on my Talk page. Again, welcome! A good mathematical resource is also Wikipedia:WikiProject Mathematics and its talk page. Enjoy! User:Oleg Alexandrov 20:35, 29 Apr 2005 (UTC) ==Empty product== :: Here is another justification, based on computer programming. Suppose you have an array of numbers x(1) ... x(10) and you want to get the sum of them and the product of them. You would do it this way (pseudocode, not WikiCode): :: sum := 0 :: prod := 1 :: for i := 1 to 10 do ::: sum := sum + x(i) ::: prod := prod * x(i) :: The empty sum is 0. The empty product is 1. Someone may want to write this up for the article. I don't want to because I don't want to take any heat. User:Bubba73 02:44, 21 Jun 2005 (UTC) It's already in the article. It's the section titled ''A conceptual rationale''. User:Michael Hardy 22:52, 21 Jun 2005 (UTC) :W/o looking, isn't that the calculator example? I think that is a bit different. This is actually done a lot, there aren't any calculators like the one in the article. No — it's not different except that the calculator in the example is simpler than any existing device, because it's designed as a thought experiment only for the purpose of explaining this idea. In other words, it's stripped of all complications that, although useful in other contexts, are not useful in this article. User:Michael Hardy 00:10, 22 Jun 2005 (UTC) :It amounts to the same thing, but there are differences. For one, the limited calculator seems to have been very controversial, from what I read of the old discussion. I think that the little program should not be controversial (although strangely I seem to be wrong about that!) Secondly, this is an example from actual practice, not contrived like the calculator.

I'm a freelance software developer in Brunswick, GA. My interests are mainly in math, computer science, chess, Contract bridge, music, the history of computing, and physical science. I have BS degrees in math and physics (emphasis in astronomy), a master's degree in applied math, and a MS in Computer Science. I program in Pascal programming language and Delphi programming language. I've been contributing to chess endgames on Wiki, and a few other things.
