Hello, I'm DVdm. I noticed that you added or changed content in an article, E (mathematical constant), but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. You can have a look at referencing for beginners. If you think I made a mistake, you can leave me a message on my talk page. Thank you. DVdm (talk) 09:02, 4 March 2022 (UTC)

Hello, I noticed that you may have recently made edits to E (mathematical constant) while logged out. Wikipedia's policy on multiple accounts usually does not allow the use of both an account and an IP address by the same person in the same setting and doing so may result in your account being blocked from editing. Additionally, making edits while logged out reveals your IP address, which may allow others to determine your location and identity. If this was not your intention, please remember to log in when editing. Thank you.
