1. Scientific Notation

2. What is Scientific Notation? Scientific notation is a way of writing extremely large or small measurements. The number is written as a product.

3. What are the steps? 1. Write number such that it is between 1 and 10. 2. Write next factor as an exponent of 10 and count decimal places moved.

4. Rules for Changing Exponents If you increase the exponent, decrease the number (move decimal to the left) If you decrease the exponent, increase the number (move the decimal to the right)

5. Adding and Subtracting Using Scientific Notation If the exponents are the same it’s easy. If the exponents are not the same we have to make them the same.

6. Rules for Changing Exponents If you increase the exponent, decrease the number (move decimal to the left) If you decrease the exponent, increase the number (move the decimal to the right)

7. Multiplying and Dividing Using Scientific Notation Rule for multiplying: Multiply numbers then add exponents and then multiply the units. Rule for Dividing: Divide numbers and then subtract the exponents and then divide the units. Make sure your answer is in Correct Scientific Notation.
