Hello, I'm Jack90s15. 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 refrain from making unconstructive edits to Wikipedia, as you did at Compound matrix. Your edits appear to constitute vandalism and have been reverted. If you would like to experiment, please use the sandbox. Repeated vandalism may result in the loss of editing privileges. If your edits are intended to improve the article, please leave an edit summary explaining your motivations. — Anita5192 (talk) 15:37, 26 May 2019 (UTC)
