counting in hindi

The numbers are strings made up of numbers that are used to represent the magnitude. They are used to measure the size of a thing, the size or how small the quantity is. In math, there are many kinds of numbers, however they are classified into two major categories: the counting numbers, and scalars.

Counting numbers, Natural Numbers

They are used to count the amount of objects. These are whole positive numbers that have no fractional components. For instance, 12 cars, 45 students, three houses. For more information on this, see Counting numbers and Natural numbers.

Scalars

They are Hindi numbers that are used to determine an amount to any desired level of precision. For instance, a building's height is 12.388 meters or the speed that an airplane travels can be 810.31 km/h. They may have decimal places or fractional components. Also, see the definition of a Scalar. In this category, there are a variety of types of numbers:

  • Real numbers are those which can be positive, negative or even zero and may have decimal points or even fractional components. They are among the most popular numbers used to measure quantities. For instance, 31.88 centimeters. They typically have units. For more see Real number definition.
  • Integers are whole numbers that may be negative, positive or zero, but do not have decimal points as well as fractional components. They're similar to counting numbers , but they can also be negative. For more information, see Integer Definition.
  • Negative and positive numbersPositive number are those that are believed to be higher than zero. A positive number that is large is greater than a smaller one, for instance +12 is greater than +2. For more information, refer to the Positive Number definition.Negative numbers are ones that are considered to be lower than zero. They are often thought of as a deficit or debt. For instance, if the wallet you carry is full and owe someone a sum of $12 and you imagine your wallet being negative in the amount of the amount of $12. This means that you have more than zero dollars. For more information on this, see Negative Number Definition.
  • Rational as well as Irrational number Rationalnumbers are numbers which can be described in the form of the ratio between two numbers.
    The word "rational" comes from the word 'ratio'. For instance, that number 0.5 is rational since it is written as half of the number . For more see Rational number definition.Irrational numbers are those that are not rational, that is those that cannot be written as the ratio of two integers. For more information, see Irrational numbers definition.
  • Imagineary numbersImaginary numbers are required to determine how to find the square root for negative numbers, something that is not usually possible. For instance, that the square root for -16 could be written as 4i 4i, in which the letter i represents the sign for square roots of a negative one. For more information on this, see the definition of an imaginary number.
  • Complex numbersRemember that real numbers are those that reside on a line of numbers. Complex numbers extend this concept to numbers that are located on a flat, two-dimensional plane. Complex numbers comprise two partscalled the imaginary and real parts. See Complex number definition.
  • Primitive numbers are int which does not have any factors (Integers that divide a number without leaving a remainder) apart from one and itself. Also, it can be divided by only one factor and the number itself. 17 is an integer prime. It isn't because it is able to be divided into 2, 4, and 8.A Composite number can be described as one that isn't prime. The number does contain factors, which is why it is the opposite of the prime number. See Composite number definition.

Number notation(counting in english)

There are a variety of ways numbers can be written or illustrated.

  • The number line is a visual way of displaying the numbers, by placing them in an uniform line, typically having zero at the center and positive numbers to left and negative ones on the left.
    For more information, refer to the Number line.
  • Decimal notationThe most commonly used way for representing real numbers. A string of digits , and a decimal mark (dot). The digits left of the dot are increasing powers of ten. Digits to the right are increasing negative powers of ten. Example 836.33 , -45.009.
  • FractionsA fraction is a two-dimensional quantity that are written one over the other. It indicates how much of totality we possess. For instance, we could be able to have 3 quarters a pizza, or 34 of the pizza. For more information, refer to Fraction definition.
  • Normal format (Scientific notation)For extremely large and extremely small numbers decimal notation isn't the most efficient. A number in normal form is composed of two parts that are a coefficient and the exponent (power of 10). For instance the distance to the Sun is 9.3000000 miles. It can be conveniently written as 93000000x10 6. miles. The coefficient is 93 and six is the exponent. For more information, refer to the the normal form (scientific note).

Certain numbers aren't numbers in any way

Sometimes, numbers are used to identify objects. Instead of determining how large an object is, or counting it, they are used to identify things in the real world. For instance, a student ID number isn't used to determine anything. It's just an array of numbers that identify a specific student.

It is absurd to attempt to do arithmetic using these numbers. Dividing a student's number by two or determining an equation for the square root in a telephone number is not a good idea.
