in reply to Operators: arithmetic and otherwise

"You can also use an and to allow something to execute only if the first criteria evaluates to 0; $isMonday and print "Today is Monday\n";" if the first criteria evaluates to 0, the followed command will not execuate. In this situation, an "or" should be used instead of an "and".
