[edit] Hello, I'm Jim1138. I noticed that you recently removed some content from Fundamental theorem of calculus with this edit, without adequately explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an edit summary. If this was a mistake, don't worry, the removed content has been restored. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. Jim1138 (talk) 10:28, 21 May 2016 (UTC)
Please do not add or significantly change content without citing verifiable and reliable sources, as you did with this edit to Fundamental theorem of calculus. Before making any potentially controversial edits, it is recommended that you discuss them first on the article's talk page. Please review the guidelines at Wikipedia:Citing sources and take this opportunity to add references to the article. Jim1138 (talk) 10:53, 21 May 2016 (UTC)
Fundamental theorem of calculus
[edit]I undid your edit to Fundamental theorem of calculus as it was unreferenced and as you didn't explain your reason in an wp:edit summary. Regarding citations: Adding references is how we ensure that content is valid. Without references, a reader can not easily validate information and there is no presumption of accuracy. This is covered by the Wikipedia policy of wp:verifiability. Please wp:cite your edits with wp:reliable sources. See Help:Citation Style 1 and wp:Inline citations. An example: Steve Jobs (1955-2006)<ref>{{cite web|url=http://www.cnn.com/1234 |title=Steve Jobs obituary |author= Walter Green |work= [[CNN]] |date= November 15, 2006 |accessdate= February 2016}}</ref> which generates: Steve Jobs (1955-2006)[1] with the footnote automatically added to the References section ({{reflist}}
needed). Remember, unsourced content may be removed.
It can be complicated and there is help available. So, if you have any questions, please ask at the wp:Teahouse Thank you Jim1138 (talk) 10:55, 21 May 2016 (UTC)

I don't understand, can you translate it in Chinese?
