One Sided Limit Error on the Prime

[chazzs]

That I new. I just assumed unchecking the Complex and i boxes in CAS would have resulted in not allowing complex values. I guess I'm not entirely sure what the Complex check box does besides allowing the factorization of x^2+4 (and finding complex solutions.) I assumed some consistency across the board, especially if HP wants to make its way back into the educational field, which I hope is the current train of thought.
