What it means to a mathematician 'to exist' is
quite a controversial problem
"To exist" means that it may be given a name, and that one
may speak about it in statements or formulas or use it in
a term to denote something.
For example, one might choose to assume that the solution
of "x+1=0" exists.
Then one might give it a name. Let's do this. I call it "E".
I may speak about it in a statement: "E is a value.".
I may use it in a formula: "E < 0".
I may use it in a term: "2*E".
