I'm writing a script and I would like to pass the results from bc into a variable. I've declared 2 variables (var1 and var2) and have given them values. In my script I want to pass the results from bc into another variable say var3 so that I can work with var3 for other calculations.

Hi,
On a hosted linux environment which I have very little control over, I have a PHP script that takes in X number of floats, performs Y number of simple recursive arithmetic calculations, and produces some output for display to the user.

Code:
x=6

echo $z
When I run the script the return is
expr x + y
I am stuck as to why it's not running the addition and just returning the text.
