i have this one
OM5= NOT ( A OR (B AND C)) OR D
i provided i photo of it. https://i.sstatic.net/opS1I.png
I used different calcs that were online and all gave me this result http://www.wolframalpha.com/input/?i=not+(a+or+b%26%26c)+or+d like the wolframalpha one!
But when i did it with my hand i had different results.
the result was NOT(A) AND ( NOT(B) OR NOT(C) OR D )
NOT ( A OR (B AND C)) OR D
= (NOT A AND NOT (B AND C)) OR D
= (NOT A AND (NOT B OR NOT C)) OR D
= (NOT A AND NOT B) OR (NOT A AND NOT C) OR D
That's it.
