Solving inequality in complex plane I have to graphically represent the following subset in the complex plane being z a complex number:
$A={1<|z|<2}$
However after trying to do it on WolframAlpha it says that "inequalities are not well difined in the complex plane". 
What I did previously was solve it like it was a regular inequality system in the real numbers, resulting in $b<-a+4$ and $b>-a+1$
How can I solve this? 

Hint: $|z|$ is the distance from $z$ to $0$.  So geometrically, $1 < |z| < 2$ is the region inside ... and outside ...
