User talk:180.243.0.42

Hello, I'm Materialscientist. I noticed that you recently removed content without adequately explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an accurate edit summary. If this was a mistake, don't worry; the removed content has been restored. If you would like to experiment, please use the sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks.

Please do not remove content or templates from pages on Wikipedia, as you did to Triangular number, without giving a valid reason for the removal in the edit summary. Your content removal does not appear to be constructive and has been reverted. If you only meant to make a test edit, please use the sandbox for that. Thank you.
