Re: How to force Mathematica to treat a number as positive and real?


Sorry, I notice that a special character in my reply has got scrambled 
in the email.
The character in question is the one you obtain by typing \[Element]

So, for example I meant to write:

Simplify[{Abs[a], Re[a]}, Assumptions ->
     {a \[Element] Reals, a >= 0}]
