Prove the following argument. Be sure to define predicates that you use. The domain is all people. Please indicate the law or rule being used. Everyone who likes football and lives in Seattle likes the Seahawks. Only the people who live in Seattle like the Mariners. Ella likes the Mariners but not the Seahawks.

1. Mathematical logic is a subfield that considers the analysis of logical propositions for the purpose of verifying whether a statement is true or false. Furthermore, propositions can be simple or compound. In the case of compounds, they must be joined with logical operators. Consider the following simple and compound propositions below. Also consider the “>” sign meaning “greater than”. ( ) It is not true that 11 is an even number ( ) It is not true that 11 is a prime number ( ) (2 + 4 = 6) and (1 > 3) ( ) (2 + 2 = 4) ou (3 + 3 = 7) ( ) Brasília é a capital do Brasil ou 2² = 5 Mark the alternative that shows the sequence of logical values, in order, of each proposition. Consider “T” as “true” and “F” as “false”. A V – F – F – V – V B F – V – F – V – F C V – F – V – F - V D F – V – V – V - F E V – V – F – V - F
Define denotational semantics for the language of octal (base 8) numerals. Use the definition to find the value of “752”. You must define M_dec as a semantic function that maps syntactic objects written as octal numbers (with no decimal points, i.e., no fractions) to a set of non-negative decimal integer values. For Example, given the octal string “752” then: M_dec(“752”) would return 490 as its equivalent decimal value.
