Mathematical Logics - Essay ExampleIt does not only promote proper abstract thought but it also enhances a proper use of common sense.The total of numbers available for Andy are Belles 3+4+7=14 or Carols 4+6+8=18 or the sum on my card=?Let the sum of Andys card game be A, Sum of Belles cards is B and some of Carols cards be C and the sum of my cards is M. So M=B or M=C. This is because we are told that there are at least two card sums which are equal. The sum of Carols cards and Belles cards are not equal(B C).This elbow room that the sum of my cards is either equal to Carols or Belle.This reasoning is derived from the fact that Andy admitted that there are two people with an equal sum of cards.The union of odd numbers is 1,3,5,7 and 9.Also, Belle admits that he can see all the five odd numbers, what does this imply? Firstly Belle cannot see 3 and 7 since he is the star possessing these subsets. Secondly, it means that the odd numbers Belle sees are 1, 5 and 9.It is obvious tha t Andy possesses the card with 1 on it. Who has 9 and 5? Since there is no one else in the game, it is obvious that I possess cards with 9 and 5.From above, the sum of my cards so far is 9+5=14.I still have another(prenominal) card to add to this which means the sum of my cards can never be 14.That is M14.Therefore it is obvious that the sum of my cards is 18 since it is the only remaining (M=18).14+X=M=18.X=18-14=4.This means my third card is 4.Therefore my cards are 9, 5 and 4.In conclusion from the above calculations and reasoning, it is evident beyond reasonable doubt that I have a 4, a 9 and a five. These answers have arrived after a rigorous process of extensive logical reasoning and application of a little bit of Boolean algebra. The fact that there were three sets of cards visible to Andy, that is mine, Carol and Belle enable me to come down to the situation that the actual cards available to Andy are two sets.
