The definition of ''or'' when sketching a set

z is the set where Re(z)<1 or Im(z-1) does not equal zero.

so my question is when they say ''or'', do they also mean the points that satisfy both sets or does ''or'' mean exclusive to one set?

Re: The definition of ''or'' when sketching a set

In all of mathematics, "or" usually signifies what would be often denoted as "and/or", so in this case z is something that satisfies at least one of those constraints.
