Hello, I'm DVdm. Your recent edit to the page Mathematical fallacy appears to have added incorrect information, so it has been removed for now. If you believe the information was correct, please cite a reliable source or discuss your change on the article's talk page. If you would like to experiment, please use the sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you.

Note: unlike your claim, √1 has only one value. See article Square root: "Every positive number a has two square roots: √a, which is positive, and −√a, which is negative." - DVdm (talk) 06:59, 15 October 2018 (UTC)
