Examples:
1:
[FLags] Output Simplify: None. Increasing: Off
entry line: x^2+x^1-x^0 [Enter] returns x^2+x-1 (OK)
1a: [FLags] Output Simplify: None. Increasing: On
entry line: x^2+x^1-x^0 [Enter] returns x^2+x-1 (Why?)
the system (CAS) does not consider the increase flag, which must be made at the end of process, you agree with this?
1b: [FLags] Output Simplify: Minimun. Increasing: On
entry line: x^2+x^1-x^0 [Enter] returns -1+x+x^2 (OK)
1c: [FLags] Output Simplify: Maximun. Increasing: On
entry line: x^2+x^1-x^0 [Enter] returns x^2+x-1 (Why?)

2:
2a: [FLags] Output Simplify: None. Increasing: On
entry line: x^2*y^0+x^1*y^1-x^0*2*y^2 [Enter] returns x^2+x*y-2*y^2(Why?)
2b: [FLags] Output Simplify: Minimun. Increasing: On
entry line: x^2*y^0+x^1*y^1-x^0*2*y^2 [Enter] returns x*y+x^2-2*y^2 (OK)
but [For next firmware] Default X increases, it should be able to specify the variable work or main var or increasing var: X or Y, Z ...
