Scientific notation or standard form
Very large and very small numbers are expressed in scientific notation
A shortcut used for writing extremely large or small numbers is scientific notation. In this format, numbers are expressed as a product of a coefficient and a power of ten, making them easier to read and manage. For example, 3,000,000 can be written as (3 \times 10^6), while 0.00045 can be represented as (4.5 \times 10^{-4}). This method simplifies calculations and comparisons involving very large or small values.
Very small or very large numbers are often expressed using scientific notation, which simplifies the representation by writing a number as a product of a coefficient and a power of ten. For example, the number 0.000123 can be expressed as (1.23 \times 10^{-4}). This method makes it easier to read, compare, and perform calculations with extreme values.
A useful way of writing large or small numbers instead of having to write alot of zeros. Example- 5,000= 5 x 1,000= 10 to the 3rd power :)
A method of writing very large or very small numbers using powers of 10 is called scientific notation. In this format, a number is expressed as a product of a coefficient (between 1 and 10) and a power of 10. For example, ( 4.5 \times 10^6 ) represents 4,500,000, while ( 3.2 \times 10^{-4} ) represents 0.00032. This notation simplifies calculations and makes it easier to read and compare extreme values.

The main reason for using scientific notation is to express extremely large or small numbers more conveniently. It allows us to represent these numbers in a concise and standardized way, by using a power of 10. This makes it easier to communicate and work with very large or small values in various scientific and mathematical fields.
Scientific notation is a way to represent very large or very small numbers in a concise and standardized format. It involves writing a number as the product of a decimal number between 1 and 10 and a power of 10. This format is particularly useful when working with numbers that have many zeros.
It can simplify writing very large numbers. For example, a googol, which is 10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 (and there may be a mistake there!) can be written ever so simply as 1*10^100.A googol maybe a curiosity but there are physical constants such as Avogadro's number which is 6.022140857*10^23, or a light year, which is 9.4607*10^15 metres where it is easy to make a mistake in the number of zeros..
Hierarchy.
When you abbreviate very large or very small numbers, you are using scientific notation. This method expresses numbers as a product of a coefficient and a power of ten, making them easier to read and work with. For example, 1,000 can be written as (1 \times 10^3), while 0.0001 can be written as (1 \times 10^{-4}). This notation is particularly useful in fields like science and engineering.
