Explanation Whole numbers: Whole numbers are the numbers that occurs commonly and obviously in nature. Whole numbers are positive numbers including zero without any decimal or fractional parts. W = { 0 , 1 , 2 , 3 , 4 , … } Group: Group is a set equipped with any operation (like addition, multiplication and composition) that satisfies certain basic properties namely associative property, identity property, inverse property and commutative property. Closure: If a and b are an element of a set, then the result of any operation with a and b is an element of the set. ( a ○ b ) ∈ s e t Example: If one and two is the element of group, then 1+2 is also the element of the group Associative property: Associative property states that the regrouping of numbers also gives the same result. It allows us to group the numbers. It involves in the operation of three or more numbers. The numbers are grouped by parenthesis. If a , b and c are the elements of a group, then associative property for any operation is, a ○ b ○ = a ○ ( b ○ c ) Identity property: Identity property states that any operation of number with the identity number gives the number itself. There exists a number I is element in a set so that, x ○ I = I ○ x = x Inverse property: If x is the element of the set, then any operation of x with its inverse is equal to the identity element. x ○ x - 1 = x - 1 ○ x = I The identical element for addition and multiplication is zero and one respectively. Commutative property: Commutative property states that changing the order of the operand does not change the result. It allows us to rearrange the numbers. If a and b are the element of a set, then a ○ b = b ○ a Calculation: We need to check whether the whole numbers for multiplication forms a group or not. W = { 0 , 1 , 2 , 3 , 4 … . . } Closure: If a and b are the elements of whole number, then addition of any two whole numbers is also a whole number

Pidgeonhole Principle 1. The floor of x, written [x], also called the integral part, integer part, or greatest integer, is defined as the greatest integer less than or equal to x. Similarly the ceiling of x, written [x], is the smallest integer greater than or equal to x. Try figuring out the answers to the following: (a) [2.1] (b) [2] (c) [2.9] (d) [2.1] (e) [2] (f) [2.9] 2. The simple pidgeonhole principle states that, if you have N places and k items (k> N), then at least one hole must have more than one item in it. We tried this with chairs and students: Assume you have N = 12 chairs and k = 18 students. Then at least one chair must have more than one student on it. 3. The general pidgeonhole principle states that, if you have N places and k items, then at least one hole must have [] items or more in it. Try this out with (a) n = 10 chairs and k = 15 students (b) n = 10 chairs and k = 23 students (c) n = 10 chairs and k = 20 students 4. There are 34 problems on these pages, and we…

The everything combined problem Suppose that a computer science laboratory has 15 workstations and 10 servers. A cable can be used to directly connect a workstation to a server. For each server, only one direct connection to that server can be active at any time. 1. How many cables would you need to connect each station to each server? 2. How many stations can be used at one time? 3. How many stations can not be used at any one time? 4. How many ways are there to pick 10 stations out of 15? 5. (This one is tricky) We want to guarantee that at any time any set of 10 or fewer workstations can simultaneously access different servers via direct connections. What is the minimum number of direct connections needed to achieve this goal?
