Hello. This is a message to let you know that one or more of your recent contributions, such as the edit you made to Calculus, did not appear to be constructive and have been reverted. Please take some time to familiarise yourself with our policies and guidelines. You can find information about these at our welcome page which also provides further information about contributing constructively to this encyclopedia. If you only meant to make test edits, please use your sandbox for that. If you think I made a mistake, or if you have any questions, you may leave a message on my talk page. ''The claim that the Indian approach was "not rigorous" is a long-standing one in this article. You cannot simply reverse that claim to "rigorous" without talk page discussion and reliable sources'' Meters (talk) 18:50, 6 October 2021 (UTC)

Please do not add or change content, as you did at Calculus, without citing a reliable source. Please review the guidelines at Citing sources and take this opportunity to add references to the article.   DVdm (talk) 13:10, 26 October 2021 (UTC)
