There are thousands of such expressions. Some are c, 2a+1, 4b+7, 100c+79, a+b, b+c, thousands more. What were the choices you had to pick from that you didn't post? all you have to know are: EVEN + EVEN = EVEN EVEN + ODD = ODD ODD + EVEN = ODD ODD + ODD = EVEN EVEN x EVEN = EVEN EVEN x ODD = EVEN ODD x EVEN = EVEN ODD x ODD = ODD Edwin
