    Sets and Basic Notations  A set is a collection of objects, and the objects in a set are called the elements of the set. Ex. {0, 1, 2, 3, 4, 5}  A pair of braces, { }, is used with words or symbols to describe a set.  In the set builder notation, the criteria for deciding whether an object belongs to a set are given. Ex. {x|x is greater than 5} where “|” is read as “such that.”  Two sets A and B are said to be equal, written A = B, if and only if A and B have identical elements. Ex. {4, 5, 6} = {6, 4, 5}  The union of two sets A and B, denoted by A B and read “A union B,” is the set of all elements that are in A or in B or in both A and B.  The intersection of A and B, denoted by A B and read “A intersection B,” is the set of all elements that are in both A and B.  An empty set is a set that contains no elements and is denoted by .  Two sets that have no elements in common are called disjoint sets.  If every element of a set S is also an element of a set T, then S is a subset of T, written S T.…

    Perfect Numbers

    Perfect Numbers

    Mathematicians have been fascinated for millenniums by the properties and patterns of numbers. They have noticed that some numbers are equal to the sum of all of their factors (not including the number itself). Such numbers are called perfect numbers. A perfect number is a whole number, an integer greater than zero and is the sum of its proper positive devisors, that is, the sum of the positive divisors excluding the number itself. Equivalently, a perfect number is a number that is half the sum of all of its positive divisors, including itself. For example; 6, the first perfect number, its factors are 1, 2, 3 and 6. So, 1 + 2 + 3 = 6 or alternatively (1+2+3+6) divided by 2, which = 6. The next perfect number is 28, and its factors are 1, 2, 4, 7, 14, and 28. So, if we use the method which excludes the perfect number 28, we express the equation as, 1+2+4+7+14 = 28. Or using the other method, (1+2+4+7+14+28) divided by 2, it results as 28, thus making 28 a perfect number.…
