For OAI32, in class we counted the number of transistors for gate level but now I'm counting it again and getting another result. In class we counted 8 for 3 input OR, 6 for 2 input OR, and 6 for NAND(?). Now I'm counting 8+6+4 (4 for NAND). 6 for NAND is wrong I think because even if we took an AND (which is 4+2=6) then inversed it, that would be 6+2=8, not 6. So which one is correct?
