X^* means complex conjugate of X.

I am confused. What is x^* ?

Okay, weird...just narrowed it down. In my first image I didn't include the equation as I entered it. It's a bug in how it's reading my input. Take a look at this image now, as it includes what I actually type.

And Gustavo is right'o! But not exactly as I entered it.

Daniel, you might want to look at this again. Look at my numerical example I provided. Then go ahead and enter the same calculation using just x instead of the complex conjugate of x. It won’t cancel in either of these, for the same reason it shouldn’t for the former. It’s inconsistent.

Ah, yes. Bad precedence. I filed a bug report for this.

(2 (5 - I 7) - 1) is not the same as 2 ((5 - I 7) - 1)

Common factors are cancelled (standard in rational function fields). Think of it as a removable singularity, one that, well, got removed.
