Subject: Using "not" in compound conditions

Hi
 I am still a beginner at Ruby, and have just arrived at this in my 
learning curve.

 I would like to code
     not(condition1) && not(condition2)
 This is accepted in irb -
     not(condition1) && condition2
 but this produces a syntax error
     condition1 && not(condition2)

 I do not get it (obviously). I do not even know what to ask in reply -
 How do I code a compound condition, without introducing extra wrappers 
like -
     (not(condition1)) && (not(condition2))

 Regards
 Peter
