If not, please do correct me.

The question is,

The complex number z is given by z = 1 - i. Express in the form p+qi where p and q are real and find the modulus and argument of .

I don't know, I just feel that something is not right here even though I've checked many times. Here's my answer:

Ok. I've figured out how to use LaTex.
