DIFFERENT FORMS OF NUMBERS

Different forms of numbers:

In mathematics we have different forms-of-numbers. The classification of numbers are natural number, whole number,Integer, fractions, decimals, percents, irrational and rational numbers, real numbers and complex numbers.

Numbers, are classified according to their types.

Natural numbers:

Set of all numbers which is beginning with 1,2,... is called as Natural numbers

Whole numbers:

Set of all numbers which is beginning with 0,1,2,3...is called as whole numbers

Integers:

Integers are set of all whole numbers and their opposites. We are using number line to denote integers....-3, -2, -1, 0, 1, 2, 3....

Fractions:

Fractions are numbers expressed as the ratio of two numbers, and are used mainly to express as a comparison between a part and a whole. …,-1, -¾,-½, -¼, 0, ¼, ½, ¾,1,…..

Decimals

In this type the numbers always containing point.If we multiply the decimal with 10,100, 1000 or 10000 like that the decimal will move from right side. The decimal point is helping us to keep track of where the ‘ones’ place is. That is placed to the right of ones’ place. When we move right from the decimal point, each number place is divided by the number "10".

..., -0.5, -0.25, 0, 0.25, 0.5, ...

Percents

Percentage is the way of representing the numbers in terms of fraction of 100. We can split the word "PERCENT" as "PER + CENT". That means per hundred. Usually, in examination marks scored by the students is represented as percentage. That is, how many marks the student has scored out of 100.

25/100= 25%

Rational numbers

In our number system we are representing the rational number in the form of fraction like a/b.

1.5=3/2

Irrational numbers

An irrational number is any real number which cannot be expressed as a simple fraction or rational number. Π, √2 are some examples or irrational numbers.

Real numbers

All numbers including positive integers, negative integers, rational numbers, irrational numbers, are called real numbers.

It is usually denoted as ℝ

Complex numbers

Complex number is a combination of real and imaginary numbers. It is usually expressed in the form a+ib where a is the real number and b is the complex number. Related topics
