[edit] Divisor
Hi. I undid your edit at divisor, because, as far as I am aware, 0 is indeed a divisor of zero. No problems of dividing by zero show up, and the definition works just fine. Wonder what you think.
By the way, it is good if you use an edit summary when you contribute, and also, it is good if you use the notation Z or 
for integers, than just Z. These are two small tips. :) Welcome! Oleg Alexandrov (talk) 21:52, 31 January 2006 (UTC)
- I'm now studing CS. I've finished electrotechnic high school. Mathematic was my pretty favorite object in high school. Also, I've get some price at math contest during it. I write this for reason that you can see that I'm not so unrelevant - not for reasons of glorifing myself.
- I do not have time to read about you. To get some knowledge about you. But, what you did make no sense. I think that still in elementary school teacher said that no one number can be divided by zero. So, please turn back what you did.
- Try to divide an apple to no parts. How many you can get? Try to divide to one part. It's goes. About black board notation: I'm pretty new at Wikipedia and I still do not have quite technical knowledge about writing in it. Please, if you want to answer me - ansver at my pages.

- I will reply on your talk page too. The thing is, you don't need to divide by zero to deal with divisors. I would suggest you read carefully the definition in divisor, then we can talk. :) Oleg Alexandrov (talk) 16:03, 1 February 2006 (UTC)
[edit] Natural number vs positive integer
I undid your replacement at Chinese remainder theorem of "positive integer" with natural number. The concept of natural number is ambiguous, it may mean either positive integer or non-negative integer. For that reason, saying "positive integer" is preferred.
By the way, it is good to use an edit summary at all times, explaining what you changed and why. Just a small suggestion. :) Oleg Alexandrov (talk) 16:55, 16 February 2006 (UTC)
We have always learnt that natural numbers are 1,2,3 and so on. That 0 is integer. I think that we have problems with our science that is different than the rest of the world. Č;-) I doubt that so fundamental things like natural number are ambiguous defined in science like mathematics. --unsigned by Cikicdragan
- You may want to read natural number. Things are a bit more compliated than that; different areas of mathematics use different definitions. Oleg Alexandrov (talk) 18:15, 16 February 2006 (UTC)

- Now I understand why all this. I suppose I will tell that to my professor. I've thought that are fundamental things that are not so easly changable, so I've thought it is redundant to write "positive integer". Sorry. After those two incidence I will be more mindful when I see something strange to me at Wikipedia, especially in Wikimath. :)
- Greetings
