You know what that ' (prime) symbol means?
(I mean, now, of course, even in Maths terms...)

terenzreignz · Answer

It means "complement"
In Semi-English, semi-Mathematics language, M' means the set of all elements in the universal set and outside the set M.

In English, the gist of it is the set of all elements not in M.

So...what are NOT negative integers? (but in U)

dan815 · Answer

does M' mean not M

terenzreignz · Answer

More or less @dan815 
though not exactly...

jhannybean · Answer

So not ~M?

terenzreignz · Answer

[Subtle Hint]
Your universal set is the set of all integers.  
Your set M is the set of all negative integers.
So set M'  =  ?

terenzreignz · Answer

For the benefit of @dan815 and @Jhannybean 
In strict terms, given a universal set U and a subset M of U, then...
$$\Large M' = \left\{x \qquad\left|\qquad x \in U \land x \notin M\right.\right\}$$
