“And now the mathematician, in one of those imaginative leaps ..., suffices to characterize mathematics as a performing art.  The limit of the sequence S_n, as n approaches infinity, the mathematician assigns to the infinite series as its sum.  Assigns?  Meaning what?  Assigns means decides, ... is so, assigns meaning acts, as in the mathematician acts to create sense where before there were only the sums tramping on and on.
