Standard Form Formula
Sometimes we come across a very large number, which needs to be written in a form much smaller and understandable by the universe. When a large number is reduced in its decimal notation accompanied by an exponential, it is called standard form. Sometimes standard form is also known as exponential notation or scientific notation.
- Step one: Put a decimal point right after the first digit of a number from its right
- Step two: Count the number of places after the decimal, that will be the scientific notation.
- Step three: Drop the zeroes if any present after the decimal at the end to the end of the number
Example: The standard form of 1220 can be written as

To accommodate the digits after decimal places we use this method.
