Hello, I'm Simplexity22. An edit that you recently made to Subtractive notation 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! Simplexity22 (talk) 02:17, 13 January 2018 (UTC)
