What Is Standard Form? Representation Of Different Numbers
Standard form is commonly used in mathematics to represent a very large number in a small number in a particular manner. It is used to convert different numbers in a very common manner. It is used on a very large scale in the field of sciences and engineering. In mathematics, the standard form converts the equation into a canonical form and a generalized form of the numbers. Scientists are also used to measuring the magnitude of different quantities. Moreover, in the field of chemistry and physics makes calculation very easier for students.
In this article, we will discuss the definition of the standard form, formula, applies it to different types, and explain the complete idea with the help of examples.

Definition of Standard Form
“The standard form is converting the larger number in smaller in the exponent of 10 and multiplying with the integer.”
The standard form is used to convert the number in the exponent of 10 and with the multiple of the integer.
The integer is greater or equal to 1 and must be less than 10. It may be positive or negative.
Formula:
B × 10n
Where B is the number such that 1≤ B < 10 and “n” is the integer (positive or negative number).
The Standard Form of Numbers
In this section, we discuss the standard form of large numbers and how we can write them for different numbers.
To write the standard form steps are given below:
1. Write the first digit of the large number from the left side.
2. Add a decimal point after the first digit.
3. Write the remaining non-zero integer after the decimal point.
4. Count the number after the first digit and write in the form of an integer in the exponent of 10
The Standard Form of Decimal Number
The decimal number is defined as the decimal point already placed in the number. (i.e. 66.67, 8273.3, 0.06732). The standard form these types of numbers is written as:
1. Firstly, write the first non-zero digit from the given number.
2. Place the decimal point after the first digit that writes first.
3. Write the remaining non-zero integer after the decimal point.
4. Count the number that is placed before the decimal point and it can write in the exponent of 10 as a positive integer. ( i.e., 66.67, 68.9367) If the number is in the form of (i.e., 0.0067, 0.00093702) then the 4th step skips and by following the above three steps similarly. Count the digits from the left side of the given number and write the exponent of the 10 as a negative integer.
Examples
