PHP Code:
#cas    testInequality():=    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: " + expr0);     expr0 := expr0  -2*x^2;      print("step2: " + expr0); expr0 := simplify(expr0); print("simplify ⇨ "+expr0);     expr0 := expr0 + 3*x;     print("step3: " + expr0); expr0 := simplify(expr0); print("simplify ⇨ "+expr0);     expr0 := expr0  -­4;     print("step4: " + expr0); expr0 := simplify(expr0); print("simplify ⇨ "+expr0);     //return expr0;     return [ expr0, left(expr0), right(expr0) ];    end;#end

testInequality();

[
expr0: (--­4+4)>(x^2+x--­4-2) ?
left: --­4+4 ?
right: x^2+x--­4-2 ?
]

This is expected
[0>(x^2+x-6), 0, x^2+x-6]

When I copied your code, the "-" symbol in front of the 4 (in "step 4") was translated to two dashes: --4. Perhaps your editor is not using the correct symbol for subtraction.
