1. The problem statement, all variables and given/known data
I'm trying to show that controlled-not gate can not be used to make toffolit gate(controlled-controlled not gate)


2. Relevant equations



3. The attempt at a solution
i'm thinking that controlled not only has +(addition modulo 2) of the inputs, it cant make X and Y for input X,Y
hence cannot make function XY+Z

but I'm not sure if this is right, and I don't know how else to go about this problem.

thanks
