For sure the article is an article(!), which means you don't know what you're writing about. You should read some posts that are been accepted as an article, telling that complex numbers have 2 types! Complex number have no 2 types! A complex number has 2 very common representations (and if you are creative enough, you can add a representation of your own). Moreover, this post accepted as an article, is just bloating the post with trivialities like 2+2=4, but 1+3=4 too! This is not an article! Maybe a technical post for naive academic purposes. I do understand the the nature of community approval here: it's voluntary (and looking for high status, right?), which means that if you don't like it, don't do it, and mainly, don't complain doing it. Right? By the way, if you cared to see the article posted by the AAC (Article Approval Community) you'd had seen an article full of problems created by them, not by me (I previewed my article, and it was OK). And with no images! And with a formatted code full of extraneous span tags! Once more, you don't understand what you're writing about. Also, if they just checked what they posted, they'd have seen the problems, but for sure, they didn't. By the way, it's the 2nd post you did against me; what's your problem? Don't you have something else (that you understand) to write about? And don't come back to tell about the voluntary work you (and others) do. I'm not interested, as much as I'm not interested in your opinion about article/tip classification. Thanks for reading. :) ADDED: by the way, I'd have down voted your post, but it's impossible. You all do rules to protect all of you right?
