Welcome!

Hello Pepito123, and welcome 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:

I hope you enjoy editing here and being a Wikipedian! Please sign your name on talk pages using four tildes (~~~~); this will automatically produce your name and the date. If you have any questions, check out Wikipedia:Where to ask a question or ask me on my talk page. Again, welcome! 

I reverted your change at square root. As we all know, the square root of 9 is 3, and that's exact, as we are not talking about computers here, but rather ideal numbers with infinite precision, see real number.

And one hint. It is good that when you contribute you put an edit summary. You should explain in there what you change, and why. Thanks a lot, and welcome! Oleg Alexandrov (talk) 02:59, 10 December 2005 (UTC)Reply

I reverted your change at Quartic equation. It was wrong to put a square root there. That expression was just a copy of the coefficient in the line above, and should not have changed. More care please, and again, please explain and summarize your edits. Thanks. Oleg Alexandrov (talk) 03:03, 10 December 2005 (UTC)Reply
