Hello, I'm Yamaguchi先生. An edit that you recently made to Cauchy product seemed to be a test and has been removed. If you want more practice editing, please use the sandbox. If you think a mistake was made, or if you have any questions, you can leave me a message on my talk page. Thanks! Yamaguchi先生 (talk) 20:53, 21 March 2018 (UTC)
