More generally, for any set Cwe define ∪C= {x (∃A ∈C) ∋(x ∈A)}. For example, if A = {1,2,6,{10,100},{0},{{3.1415}}}then ∪A = {10,100,0,{3.1415}}. There are a number of variants of this notation. For example, suppose we have a sSet of 10 sets C= {A1,...,A10}. grass valley is in what county https://welcomehomenutrition.com
