Two high-class articles are the [[WP:FA|featured articles]] (FA) and [[WP:GA|good articles]] (GA). Wikipedia has an essay about the differences between [[WP:GVF|GA and FA]]. Still, it does not describe very specifically until [[Wikipedia talk:Featured article candidates/archive94#|I asked again because of both GA and FA's evolutions over time]]. [[WP:FL|Featured list]] is similar to the featured articles, but their difference is that the featured list focuses on the list-based article. This is similar to defining what [[WP:FP|featured pictures]] is. Out of '''{{NUMBEROFARTICLES}}''' articles on Wikipedia, there are '''{{formatnum: {{GA number}}}}''' good articles, '''{{formatnum: {{FA number}}}}''' featured articles, and '''{{formatnum: {{FL number}}}}''' featured lists. Because this focuses on mathematics, the following are the numbers of [[:Category:GA-Class mathematics articles|GA]] and [[:Category:FA-Class mathematics articles|FA]] based on their categories. Out of more than '''+29,000''', there are '''195''' good articles, '''31''' featured articles, '''4''' featured lists, and '''64''' featured pictures. Over time, the number has significantly changed by focusing on both categories or by presumption by looking at [[WP:GAN#MATH]]. This is intended to complete the list of high-class mathematics articles, although we have [[Wikipedia:Good articles/Mathematics]]. | __NOTOC__ '''High-class mathematics articles''' {{piechart |[ {
