Hello. Thank you for your contributions to Wikipedia.

I noticed your recent edit to Affine transformation does not have an edit summary.&#32;Please be sure to provide a summary of every edit you make, even if you write only the briefest of summaries. The summaries are very helpful to people browsing an article's history.

Edit summary content is visible in:


 * User contributions
 * Recent changes
 * Watchlists
 * Revision differences
 * IRC channels
 * Related changes
 * New pages list
 * Article editing history

Please use the edit summary to explain your reasoning for the edit, or a summary of what the edit changes. You can give yourself a reminder to add an edit summary by setting. Thanks! — Anita5192 (talk) 03:05, 29 June 2019 (UTC)
