Introduction to the new subject!

Hi! I write this post to tell you that the blog is going to change it´s topics, as I won´t have calculus class anymore(well, until calculus 2). The blog now it´s going to be about different topics, as it´s a project for comunication skills also, there will be one post per week. This week I will upload two posts, one of them for the past week. In the third trimester, the post will be about algebraic stuff.
Thanks!
