Numbers:

A number is an arithmetic value used to count things like date and times. Numbers are also called numerals. We use these in our day-to-day lives. We cannot easily do everything without numbers. We use the digits from 0 to 9 to form all other numbers.

Number Names:

Number names are used to represent numbers in alphabetical format. A specific word is used to refer to each number. To write a number in English words, we should know the place value of each digit in the number.

Ex: In the numbers' names form, 23 is written as “twenty-three.”

Natural numbers:

Natural numbers are the numbers that contain the positive integers from 1 to infinity. Natural numbers are denoted by “N”.

N={1,2,3,4,5,.............}

Whole numbers:

Whole numbers are the numbers that contain all natural numbers, which include “zero(0)”. It is denoted by “W”.

W={0,1,2,3,..............}

Integers:

Integers are the numbers on the number line that contain both positive and negative numbers, including 0. It is denoted by “Z”

Z = {.................,-3,-2,-1,0,1,2,3,..................}

Positive integers: 1,2,3,.........., also known as natural numbers.

Negative Integers: ………,-3,-2,-1.

Fractional And Decimal Numbers:

Fractions are part of the whole. They are represented by numbers that have two parts to them and are separated by a bar. There is a number at the top, which is called the numerator, and the number at the bottom is called the denominator.

Ex:

(numerator)1/4 (denominator)

Decimals have a whole number part and a fractional part. These parts are separated by a decimal point.

Ex:

Decimal Point

Whole number part 20 . 5Fractional part

Real numbers:

All the positive and negative integers, fractional, and decimal numbers without imaginary numbers are called real numbers. It is denoted by “R”.

R={-4,0,3,⅓,4.89,...........}

Rational numbers:

Any number that can be written as a ratio of one number over another is written as a rational numbers. This means that any number that can be written in the form of p/q. This is denoted by “Q”

Irrational numbers:

An irrational number is one that cannot be expressed as a ratio of one number to another. It is denoted by “Q”.

Complex numbers:

The number that can be written in the form a+ib where “a” and “b” are called real numbers and ”i” is called imaginary, is known as a complex numbers. It is denoted by “C”.

Ex: 3+4i, 5+6i, 0+7i, 8+0i,........

Imaginary numbers:

The imaginary numbers are the complex numbers that can be written as the product of a real number and the imaginary unit “i”.

Ex: For example, the imaginary number of 3+4i is 12 (34).

Even numbers:

A number that is exactly divisible by 2 is called an even number. It is also called a number that leaves a remainder when it is divided by 2. Simply all multiples of “2”.

Ex: 2,4,6,.........

Odd numbers:

A number that is not exactly divisible by “2”’ or a number that leaves the remainder “1”’ when it is divided by “2” are called odd numbers. Simply not multiples of “2”.

Ex: 1,3,5,..........

Prime numbers:

Prime numbers are the numbers that have two factors only, that is 1 and the number itself.

Ex: 2,3,5,...........

Composite numbers:

Composite numbers are those that have more than two factors.

Ex: 4,6,8,9,.........

Note: ”1” is neither prime nor composite.

Cardinal and Ordinal Numbers:

Cardinal numbers are the numbers that are used to count any object. Any natural number that is 1,2,3,4,..

An ordinal number is a number that denotes the position or place of an object, such as 1st, 2nd, .....
