# Scientific notation

Updated: 12/26/2023 by Computer Hope

A method of writing a large or small numbers, **scientific notation** is an integer between 1 and 10 multiplied by the power of 10. For example, "987,000,000" could be written in scientific notation as *9.87 * 10 ^{8}*,

*9.87 * 10^8*, or

*9.87e+8*.

## Steps to convert a real number into a scientific notation

- Place a decimal point after the first digit. If we were using the same number we used above, the decimal point would be placed after the nine.
- Complete the remainder of the number excluding the trailing zeros. In our example, 9.87 is known as the coefficient.
- To find the exponent, count all the digits up to the decimal point. Because our number was nine digits long, this would mean we have an exponent of eight.

## Steps to convert a scientific notation into a real number

- Assuming our scientific notation was "8.01+E5."
- Calculate
*8.01 * 10 * 10 * 10 * 10 * 10*(eight multiplied by ten thousand). Or, move the decimal five places to the right. - The answer for this scientific notation should be "801000."

or

- Open the calculator on your computer.
- Enter
*8.01* - Press
`E`for exponent. - Enter 5 and press
`Enter`.

## Scientific format

In Microsoft Excel and other spreadsheet programs, **Scientific** is a number format that allows numbers to be formatted in scientific notation format.
