# How do you write 100,000,000,000 in scientific notation?

##### 1 Answer

#### Explanation:

Scientific notation is used to transform big or small numbers to decimal form. Numbers are written in this form:

where *m* is a real number and *n* is an integer

To write the scientific notation of a number, you have to move the decimal point to a specific significant figure then count how many places did you move the decimal point until it reached the first significant number. This then becomes the exponent, *n*.

Moving the decimal point from **right to left** would result to a **positive** exponent. Moving the decimal from **left to right** on the other hand would result to a **negative** exponent

For this example,

move the decimal (**left** until all zeros are placed after the decimal.

Now, counting the places where the decimal point has moved

using this information we can conclude that,
