Thank you for your contributions&#32;to Invertible Matrix, but we are trying to write an encyclopedia here, so please keep your edits factual and neutral. Our readers are looking for serious articles and will not find joke edits amusing. Remember that Wikipedia is a widely used reference tool, so we have to take what we do here seriously. If you'd like to experiment with editing, use the sandbox instead. Thank you. Plutobutbigger :) (talk) 15:42, 16 September 2021 (UTC)
