The Kernel#system method returns a boolean datatype, that is -- true if 
the command was ran sucessfully, false otherwise.

Use backticks or %x{} is you want to store the output

var = `#{ foo + bar + baz}`  # as Marc said
var = %x{ #{foo + bar + baz} }  # Im pretty sure that works, sorry I 
can't test it right now.
