In the formula

Extension × Intension = Implication

we may have the values

(1)	0	×	0	=	0
(2)	0	×	n	=	0
(3)	0	×	∞	=	0
(4)	0	×	∞	=	n
(5)	0	×	∞	=	∞
(6)	n	×	0	=	0
(7)	n	×	n	=	n
(8)	n	×	∞	=	∞
(9)	∞	×	0	=	0
(10)	∞	×	0	=	n
(11)	∞	×	0	=	∞
(12)	∞	×	n	=	∞
(13)	∞	×	∞	=	∞

(7) will be the case with any ordinary symbol.

(4) is the ordinary nothing.

(10) the ordinary being.

These are the cases when implication is n. Now for those where is is 0.
