Is it try that if P -> Q, then ~Q -> ~P always?

Let's see!

Background: A -> B is an abbreviation for ~A OR B.  See https://mathworld.wolfram.com/Implies.html

| P | Q | ~P | ~Q | ~P OR Q = P->Q | ~~Q | ~~Q OR ~P = ~Q -> ~P | Same?
-----------------------------------------------------------------------
| T | T | F  | F  | F OR T  =  T   | T   | T OR F    = T        |   ✅
| T | F | F  | T  | F OR F  =  F   | F   | F OR F    = F        |   ✅
