3. Scientific Notation: Add and Subtract Use the on the 10s to get the Add / Subtract the Trick: Always choose the Example: the same exponent higher exponent exponents properties numbers ?

4. EXAMPLES OF APPLICATION

5. Add

6. Subtract

7. Scientific Notation: Multiply/Divide Multiply / Divide the Use the on the 10s. numbers exponents properties

8. EXAMPLES OF APPLICATION

10. 4 – (-3) = 4 + 3 = 7

11. Answer not in scientific notation If you final answer is close to scientific notation, but not in scientific notation, then convert using exponent properties

12. . - 6 + (-3) = - 9

13. . - 6 – (-2) = - 6 + 2 = - 4
