Hello, I'm David Eppstein. I wanted to let you know that one or more external links you added to Zero-product property have been removed because they seemed to be inappropriate for an encyclopedia. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page, or take a look at our guidelines about links. Thank you. —David Eppstein (talk) 18:16, 9 July 2020 (UTC)
