Devano Understood - pretty much as long as the values of 1, + and = are what they are in arithmatic the answer will remain 2. I diddnt understand the 1 + 1 = 0 part, If I understood correctly, I assume you are using binary here with boolean operators as per your description of the swtich but I think here there is no plus, your example uses binary with boolean operators, and, nand.... so we cant really use plus to describe this. Also, flipping the switch twice is not same as 1 + 1. When you flip a switch twice you are doing boolean and and that is 1 and 0(notice I diddnt use plus) = 0. In boolean and operator, only 1 + 1 = 1 every other combinataion gives the result of 0. Makes sense? I am OK with Binary but my overall question is whether 1 + 0 can equal to anything else or not.
