Hi,

I was wondering if there is any way to tell mathematica that a variable is always real without having to use the assumptions-function within every calculation? For example, I want to simplify multiple complicated expressions, and I'd like to do something like:

"Declare that x is always real"
Simplify[f(x)]
Simplify[y(x)]
...

and not

Simplify[f(x),x e Reals]
Simplify[y(x),x e Reals]
...

Thank you!
