Hello, I'm Moriwen. An edit that you recently made to Matrix multiplication seemed to be a test and has been reverted. If you want to 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! — Moriwen (talk) 14:46, 23 September 2023 (UTC)
