0 votes 0 votes If we remember in exam(subconscious) then good for us otherwise mathematic calculation(conscious) is always saviour NAND Are they equal (a nand b) nand c = a nand (b nand c) ? //to check associativity case 1: a=0 LHS=1 RHS=1 case 2: a=1 LHS= b+c’ RHS=bc As atleast one case fails . Therefore not associative. minimalist answered Dec 28, 2023 minimalist comment Share Follow See all 0 reply Please log in or register to add a comment.
