Hello, I'm Anita5192. I noticed that you recently removed content from Matrix (mathematics) 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. — Anita5192 (talk) 16:29, 3 February 2020 (UTC)
