project HP-PRIME CAS in the classroom

[compsystems]

Hello, hp-prime developer team.

Sorry for my bad English

I want to start a project in my universityapply CAS technology in the classroom, especially with calculators.

The institution will acquire a full lab of Hewlett-Packard calculators plus a physics lab kit.

My previous and current requests for upgrades on the CAS and user interface on HP-Prime are intended to get better results of the project, I hope they can be incorporated into future firmware versions

A list of important requests

1: Improve the history view (PRETTY-PRINT)
In the following graph it is observed that the expressions of extraction of elements with AT is not a standard mathematical notation, please improve the view as a subscript since the current one is very confusing for the students





2: I will create some scripts, programs, documents, videos etc. in spanish, but I need some new incoming commands on the history as ENTRY (#) ANSWER (#).

The code in the following script would be reduced and would be easier to understand if the ENTRY (#) ANSWER (#) commands were built-in.

PHP Code:

{ y = x^2, y = 2*x + 3 };
subst(Ans[2],Ans[1]);
x^2 = 2*x + 3; 
Ans - (2*x + 3); //returns (-2*x-3+x^2) = (2*x+3-2*x-3)
simplify( Ans ); //returns (x^2-2*x-3) = 0
factor(Ans); //returns (x-3)*(x+1) = 0
{ (part(left(Ans),1)) = 0,(part(left(Ans),2)) = 0 } //returns { x-3 = 0, x+1 = 0 }
{ Ans[1]+3, Ans[2]-1 }; //returns {(x-3+3) = 3, x = -1}
simplify( Ans ); //returns { x = 3, x = -1 };
subst(y = x^2, Ans[1]); //returns y=9
subst(y = x^2, {x=3, y=9}); //returns 9=9 (verdad)
{ x = 3, x = -1 };
subst(y = x^2, Ans[2]); //returns y=1
subst(y = x^2, {x=-1, y=1}); //returns 1=1 (verdad) 


3: It is required that the terminal view, print in PRETTY-PRINT and can read a data from it, for the purpose of creating educational programs step by step and easy coding

Thanks
