Following this way, neutrosophic logic has the classical logic as subset. However, in mathematics, all the affirmations must be proved first to be accepted, so the claim that the neutrosophic logic encompass classical logic must be also proved. Thus, this paper show that the main properties of the classical logic hold when translated to neutrosophic form at propositional level. 2020 22 31 428 https://creativecommons.org/licenses/by/4.0/ 10.54216/IJNS.060104 https://www.americaspg.com/journal/21/article/428 https://www.americaspg.com/storage/6462.pdf
