Its value is calculated according to the tables as (~~1) x 1 = (~2) x 1 = 0 x 1 = 1 The assignment also receives 0 > (~~0) of the formula p > ~~p the value 0 x (~~0) = 0 x (~1) = 0 x 2 = 1. If the value is different from 0, there is no designated formula regarding our table. >Formulas.}, note = { T I Chr.
