The Basics and Background Information
• Scientific notation is used to represent very large or very small numbers.
• A number written in scientific notation is the product of two factors — a decimal greater than or equal to 1 but less than 10, and a power of 10
(e.g., 3.1 × 105 = 310,000 and 2.85 x 10 −4 = 0.000285).

The topic: What is it and what will we learn?
Look at exponents in scientific notation first. If they are different, order by exponent. If exponents are the same, then order by mantissa.
