Hello, I'm DVdm. I noticed that you made a change to an article, Dot product, but you didn't provide a source. I’ve removed it for now, but if you’d like to include a citation to a reliable source and re-add it, please do so! If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. DVdm (talk) 12:51, 21 August 2021 (UTC)


 * The edit I provided is not a citation of any scientists nor a quotation. Is it not allowed to contribute anything which is other than citations? Prince khan official (talk) 17:05, 22 August 2021 (UTC)
 * See wp:verifiability, wp:reliable sources and wp:BURDEN. All challenged content, such as this, must be cited. Hope this helps. - DVdm (talk) 21:39, 22 August 2021 (UTC)

I clearly don't see anything disputed here. So it doesn’t qualifies to be deleted Prince khan official (talk) 20:02, 24 August 2021 (UTC)
 * Please indent your talk page messages as outlined in wp:THREAD and wp:INDENT — See Help:Using talk pages. Thanks.
 * Look: . I challenged/disputed it by reverting it and saying in my edit summary: "not providing a wp:reliable source". Please read wp:BURDEN again. - DVdm (talk) 08:35, 25 August 2021 (UTC)

This is not a quotation or narration. So the edit I have done has no source from any known famous biographies. Prince khan official (talk) 02:07, 21 September 2021 (UTC)

Hello, I'm DVdm. I noticed that you recently removed content from Multiplicative inverse 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 your sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page.
