Standard Form
Using Standard Form
Very large and very small numbers can be written in standard form: m x 10

The first number 'm' is greater than or equal to 1 but smaller than 10

This is then raised to the power of another number 'n'

Positive integers of 'n' mean the number is big, while negative numbers mean the number is small
n
Standard Form: Example
This is a brief worked example, converting a range of numbers into standard form.
Standard Form and Significant Figures
