nand
     
        not and.
     
        the boolean function which is true unless both its arguments
        are true, the logical complement of and:
     
        a nand b = not a and b = not a or not b
     
        its truth table is:
     
        	a | b | a nand b
        	--+---+---------
        	f | f |    t
        	f | t |	   t
        	t | f |    t
        	t | t |    f
     
        nand, like nor, forms a complete set of boolean functions
        on its own since it can be used to make not, and, or and any
        other boolean function:
     
        not a = a nand a
     
        a and b = not a nand b
     
        a or b = not a nand not b
