Hello, I'm SemiHypercube. An edit that you recently made to Expression (mathematics) 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! SemiHypercube (talk) 12:26, 7 April 2018 (UTC)
