Laws of Logic
 
Hi could someone double check for me please that I have simplified the below expression correctly.

Thank you.

((p --> q) --> p) and (p or q).....Original Question

((-p or q) --> p) and (p or q)........Implication
(-(-p or q) or p) and (p or q)........Implication
((--p and -q) or p) and (p or q).....De-Morgans
((p and -q) or p) and (p or q).......Double Negation
(p or (p and -q)) and (p or q).......Rearranged
p and (p or q).........................Absorption
p.......................................Absorption

Final Answer = p
