To Tell the truth, there are not only amazing persons, but also good tools here that support a good environment to learn mathematics in WordPress.

Yes! WordPress can include code in the post. See the announcement “Can I put Math or Equations in my Posts? ” of FAQ. You can type the mathematical formula on the blog. Just as the article show us :

So, taking these two definitions for example,

Definition3.6 The **Jones polynomial V(L)** of an oriented link L is the Laurent polynomial in t^{1/2}, with integer coefficients, defined by

where D is any oriented diagram for L .

Definition6.6 The** r ^{th}**

**Alexander ideal**of an oriented link L is the r

^{th }elementary ideal of the Z[t

^{-1},t] module H

_{1}[X

_{∞};Z]. The

**r**of L is a generator of the smallest principal ideal of Z[t

^{th}Alexander polynomial^{-1},t] that contains the r

^{th}Alexander polynomial. The

**first Alexander polynomial**is the called the Alexander polynomial and is written Δ

_{L}(t)

(Definition Resourse: W.B. Raymond Lickorish. *An Introduction to Knot Theory*, GTM175. New York:Springer-Verlag (1997). p. 26,55.)

Using this useful Latex code… expressing and discussing mathematic are never difficulity problems here. You can also try it. But if you haven’t known what Latex would be, you may also click”LaTeX–A document preparation system” to keep close and to attach it.

p.s. As for the two definitions in the post, Gee still not catch their true meanings in my mind after typing them. If anybody can explain them more clearly…Please and please tell me.
