In this module, you can study how to write very large and very small decimal numbers in standard form, which are formats that make very large and very small numbers easier to work with.
Standard form (also called "scientific notation") is used by scientists when working with large and small numbers.
Engineers use "engineering notation", which is similar to standard form.
If a number in standard form has a negative exponent, the number is less than one.
