Solve this equation!

What is the value of: 
(1/1+(x^(-1))+(1/1+(y^(-1))=?

Re: Solve this equation!
Hi Agnishom;
Welcome to the forum! The way have bracketed or not bracketed it makes it ambiguous. Do you mean?
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Re: Solve this equation!
Than you should know that does not have a value like 3 or some number. Have you left out parts of the question?
Woops sorry, looks like it equals 1.
