How to use my calculator?
You will use the joystick in order to move around the calculator aplications and sections.
The keyboard is were you will find all the numbers, variables and options you will use during these processes.

System of Linear Equations
2) From the 3 options we have you are gonna select the first one by clicking F1.
1) To solve a linear equation system first of all you have to go to the equation section of the menu and press execute.
in this case, if the equation requires a "x" by itself put a "1" instead)
System of Linear Equations
4) Now you are going to add the coefficients. Every time you add one coefficient click execute to move on to the next.
3) In this page the calculator asks for how many unknown variables we are using, we are pressing 2 (F1).
5) When you have finished adding the coefficients, click solve (F1).
System of Linear Equations
1) Firstly you have to go to the equation section of the menu and press execute.
(In order to solve a second degree equation we are doing almost the exact same as we did before).
Equations of second degree
3) In this page the calculator asks for the degree, we are pressing 2 (F1).
2) From the 3 options we have, instead of pressing the first one we are pressing the second one (F2).
Equations of second degree
5) When you have finished adding the coefficients, click solve (F1).
4) Now you are going to add the coefficients. Remember that every time you add one coefficient click execute to move on to the next.
Equations of second degree
(you can find the variable "x" here:)
2) Then you are going to add the values where it says Y1. When you are done press execute.
1) First of all now you have to go to the graph section of the menu and press execute.
Sketching Graphics
3) Now to graph the equation you may press "draw" (F6).
Sketching Graphics
To see both X1 and X2 press the left and right side of the joystick:
2) After that, click "root" (F1).
1) After you have done all the previous process, by the time you have the graph you click "G-solv" (F5).
X-intercept
2) And right after that, click Y-ICEPT (F4).
1) You will do pretty much the same thing, press G-solv (F5).
