RE: CAS command question
For me the problem LEFT RIGHT is only visual, of course I would like it not to rewrite it to simplify.

The following code, shows that it does not matter the rewriting of the original expression, if you consider the operator.

expr0 := expr(string( simplify(left(expr0) )) + part(expr0,0) + string( simplify( right(expr0) ) ));

PHP Code:
testInequality2():=
    
begin
     local expr0
;
     print;

     
expr0 := '(3*x^2-2*x-2) < (2*x^2-3*x+4)';
     
//expr0 :=  (3*x^2-2*x-2) < (2*x^2-3*x+4);
     
print("step1:");
     print(
string(expr0)); 
     print(
"");

     print(
"step2: +(-2*x^2)");
     
expr0 := expr0 + -2*x^2
     print(
string(expr0));
     print(
"");

     print(
"step3: +(3*x)");
     
expr0 := expr0 3*x;
     print(
string(expr0)); 
     print(
"");

     print(
"step4: +(-4)");
     
expr0 := expr0 + -4;
     print(
string(expr0)); 

     print(
"");
  
     print(
"simplify → ");
     
//expr0 := simplify(expr0);
     
expr0 := stringsimplify(left(expr0) )) + part(expr0,0) + stringsimplifyright(expr0) ) );
     print(
string(expr0));  
     print(
"");
        
     return 
expr(expr0);            
   
    
end

the output is correct: 0>(x^2+x-6)
