Even Numbers

Even Numbers are those numbers that can be divided into two equal groups or pairs and are exactly divisible by 2. For example, 2, 4, 6, 8, 10, and so on. 

ODD NUMBERS

 A whole number that is not able to be divided by two into two equal whole numbers The numbers 1, 3, 5, and 7 are odd numbers.

Odd numbers are positive integers that cannot be categorized into groups of two. For example: 1, 3, 5, 7, etc. Let's visualize it using an example of footwear and cherries. Let us assume that we have footwear in counts of 1, 3, 5, and 7. On the other hand, we have cherries in pairs of 2, 4, 6, and 8. Look at the image given below in order to understand how the pairing of these numbers will work.

Properties of Odd Numbers

If you try to carry out a few arithmetic operation the odd numbers, can you come to a common conclusion of all of the numbers? Well yes, there does exist a set of properties that applies not only for the odd numbers given in the list of 1 to 200 but are applicable to any odd number that you may come across. Given below is a list of the properties that will always apply for an odd number. Each of these properties can be explained in a detailed way as given below:

• Addition: The addition of two odd numbers will always give an even number, i.e., the sum of two odd numbers is always an even number. For example, 3 (odd) + 5 (odd) = 8 (even).
• Subtraction: subtract of two odd numbers will always give an even number. For example, 7 (odd) - 1 (odd) = 6 (even).
• Multiplication: it is of two odd numbers will always give an odd number. For example, 3 (odd) × 7 (odd) = 21 (odd).
• Division: division of two odd numbers will always give an odd number. For example, 33 (odd) ÷ 11 (odd) = 3 (odd).

Natural Numbers

A natural number is a number that occurs commonly and obviously in nature. As such, it is a whole, non-negative number. The set of natural numbers, denoted N, can be defined in either of two ways: N = {0, 1, 2, 3, ..} , N = (1, 2, 3, 4, .)

Whole Numbers

Number which are started from 0 are called whole numbers.

For Example: 0, 1, 2, 3, 4, 5, 6, and 7 are all whole numbers. Numbers such as -3, 2.7, or 3 ½ are not whole numbers.

 Let's sing!

Zero, one, two, three and four.

Whole numbers are many more.

Go on! Count on my friend!

Whole numbers just don’t end!

 Fun Facts

• There is no 'largest' whole number. 
• Except 0, every whole number has an immediate predecessor or a number that comes before.
• A decimal number or a fraction lies between two whole numbers, but are not whole numbers.

POLYNOMIALS

Poly means many and nomials means terms so polynomial is working with many terms. 

           According to term they are of three types

           Monomial-one term

           Binomial  -two term

           Trinomial-three term

            According to degree they are also three types

            Linear polynomial-Degree One

            Quadratic polynomial-Degree Two

             Cubic polynomial-Degree Three
