Indeed. More wiki = more awesome.

Just a quick question: Is the Calculus development section coming up? Cause I'm chipping in for Multivariable Calculus - the course I'm taking right now.

Just curious.

You can "Add Wiki" if you want to make a Wiki page for a skill that is not listed yet. If the page is suitable, we will add it to the current map.

The Calculus section is almost fully developed for a typical high school syllabus. Over time, I will get around to adding extensions to it. Currently, I am fleshing out the Geometry and Combinatorics sections, which are much further behind.

Where can I put into the fact that "A Quadratic Equation cannot have more than 2 roots." And What Exactly does one need in Quadratics-Factoring-Medium. I am just thinking for writing up that.also..many, but the matter is I am using some proofs to prove many others so should I first make sure that those proofs exist and then go forward in writing up the the proof that I want to add to Wiki.

The first fact can be placed in Quadratic Equations - Factoring.

You can also create a new skill of "Fundamental Theorem of Algebra" and place it there, and add more details about the general $$n$$ degree polynomial.

Proofs of statements are certainly welcome, and will help provide more context to those who are interested. If you do not see a suitable place to add the proof, please use the "Add Wiki" page. Thanks!
