Law (1):
(p →
q) I ((p → q) → r) I (((p → q) → r)) → s) I ((((p → q) → r)) → s) → t) I……
Law (2):
(p →
q) & ((p →
q) → r) & (((p → q) → r)) → s) & ((((p → q) → r)) → s) → t) &……
This logic, under below conditions always is
“TRUE”:
· - p
= False and other propositions (variables) are “TRUE”
· - p
and q = False and other propositions (variables) are “TRUE”
· - All
propositions (variables) are “TRUE”
Examples:
Law (2) for three propositions (variables)Law (2) for four propositions (variables)
Law (2) for five propositions (variables)
To be continued .....
