2. What is Scientific Notation?
Simple means for writing very large or small numbers,  and involve powers of 10
For Example:
3.2 x 𝑜𝑟 x 10 −3

3. Scientific Notation Practice
Change the following numbers to scientific notation.
(1)  
ANS: *108
(2)  
ANS: 6.73*10-3
Change the following numbers to decimal notation.
(3)  7.05 x (4)  2.0367 x10-3
ANS: ANS:

4. Do-It-Yourself (DIY) 9.123 x 102 ANS: 912.3 7 x 104 ANS: 70000
Convert into Scientific or Decimal Notation for the following:
9.123 x 102
ANS: 912.3
7 x 104
ANS: 70000
1.1 x 10-2

8. Scientific Notation with Sig Figs
Multiplication and Division
When you multiply or divide 2 or more numbers, the result MUST have a specific number of Sig Figs. 
Whichever number has the least Sig Figs, the result will have the same number of Sig Figs  as it.
“EE” “xy” or “10x” on the calculator is the same as *10 power

9. Multiplication Example
Calculate the following expressions with the correct number of Sig Figs:
1)  12.3 x 20
12.3 has 3 Sig Figs
20 has 1 Sig Fig
ANS: Sig Fig
2)  12.3 x 20.0
20.0 has 3 Sig Figs
ANS: Sig Figs

10. FINAL ANS: 1.60 X 1015 3.42E5 * 4.67E9 BUT!! Sig Figs Example (Con.)
Find the solution in terms of Scientific Notation with correct Sig Figs:
3.42 X 105 • X 109
3.42E5 * 4.67E9
105 x 109=105+9=1014
1.597 X 1015
