Since the poles of a meromorphic function are isolated, there are at most [[countable|countably]] many.<sup>[citation needed]</sup> The set of poles can be infinite, as exemplified by the function
: <math>f(z) = \csc z = \frac{1}{\sin z}.</math>
 
By using [[analytic continuation]] to eliminate [[removable singularity|removable singularities]], meromorphic functions can be added, subtracted, multiplied, and the quotient <math>f/g</math> can be formed unless <math> g(z)=0 </math> on a [[connected space|connected component]] of ''D''. Thus, if ''D'' is connected, the meromorphic functions form a [[field (mathematics)|field]], in fact a [[field extension]] of the [[complex numbers]].
