Natural Numbers to Integers to Rationals to Real Numbers
... The above quote states that the natural numbers are what we were given, and all other numbers, such as integers and rational numbers, were created from them. This implies that all other sets of numbers can be formed out of the natural numbers. The object of this paper is to show the connection ...

... as A B and is defined as a set of all elements which are members of either set. They include all the elements which are in both sets. Eg: if A= {2,4,6,8} and B={ 1,3,5,7}, then A B={1,2,3,4,5,6,7,8} 2. Intersection of sets: The intersection of two sets A and B is the set of elements that occur i ...

On the Question of Absolute Undecidability
... For example, Gödel showed that in L there is a Σ12 well ordering of the reals and so this inner model satisfies ZFC + ¬PM; and (assuming an inaccessible) Solovay constructed an outer model satisfying ZFC + PM. Other notable examples of statements that are independent of ZFC are Suslin’s hypothesis, ...
