Course: Algebra II / Elementary Algebra
Topic: Exponents and Polynomials
Subtopic: Scientific Notation

Overview

Scientific notation is a specific way of writing numbers and involves positive/negative powers. It allows us to easily deal with very large (and very small) numbers without having to write out and keep track of dozens of zeros. Scientific notation opens up a world of applications especially in the physical sciences!

Objectives

By the end of this topic you should know and be prepared to be tested on:

• 6.2.4 Algebraically convert numbers in decimal form into scientific notation and numbers in scientific notation into decimal form
• 6.2.5 Perform operations with numbers in scientific notation both algebraically and electronically

Terminology

Define: decimal form (of a number), scientific notation

Supplementary Resources

You must be able to use a calculator (handheld or software) to perform operations in scientific notation. If you have a handheld graphing calculator then these sites may help:
