Substitution form paragraph
GrkCan's paragraph from July 2020 on the Substitution form really does not make a lot of sense. What is it trying to say? — Preceding unsigned comment added by 125.235.239.193 (talk) 11:08, 21 May 2022 (UTC)

The proposition "The complement of the union of two sets is the same as the intersection of their complements " is False. Boutarfa1 (talk) 12:03, 24 September 2023 (UTC)

Discussion
In the proposition "the complement of the intersection of two sets is the union of the complements of the given sets " some conditions should  be precised like that the complements of the given sets can be from the same set as well as the complement of the intersection(some other conditions are possible like when the complement of  the intersection is taken from a set that is included in the set that the   complements of the given sets are  taken from).

negative logic
I might be worthwhile mentioning somewhere here that in a digital circuit, the logical meaning of voltage levels is arbitrary: you can treat a physical high as a logical 1 or as a logical 0. To convert a '1=high' circuit to '1=low', replace each OR with an AND and each AND with an OR (treating other gates as combinations of AND, OR, and NOT). 203.13.3.93 (talk) 03:12, 19 February 2024 (UTC)

Or ...
"Not Both" is the same as "Either Not"

"Not Either" is the same as "Both Not"
