The last round of the year I have been working on the last chapter of the math book which is the per algebra. It is the most difficult and the most fun topic at the same time as I work on it. By the way in this round I have working on other topic too, which is the coordinate and the negative number. Both of the topic are my favorite topic, even it is difficult and hard to understand sometime. To study about this i have so many challenge to understand the structure of the chapter. Before I Study this topic I’m just thinking that this topic is boring but after study this, my mine have change like I mention when the first start of the sentence. Well right now I can shared some of my suggestion that i have when I study about this. So before you study about the negative number you must have a book to take note because It is really tricky for you to remember but if you have the book you can just talk note it you will be more remember about it. And when you study about the coordinate you must have to remember the plane of the coordinate. And number that is represent in each plane by the X and Y coordinate. This is mean that whenever you are study or working in a project you must take note because not will help you a lot in your study and working.
