A number is written in scientific notation when it is expressed in the form $a \times 10^{n}$ where the absolute value of $a$ is greater than or equal to 1 and less than 10. For instance, $80,000$ can be converted in scientific notation as $8\times 10^{4}$ where $8$ is a number between $1$ and $10$, and $4$ is the number of places that the decimal point has moved.
