### Section 1: Understanding Scientific Notation
**Definition:**
Scientific notation is a way to express very large or very small numbers conveniently. It is written in the form:
\[ a \times 10^n \]
where:
- \( 1 \leq |a| < 10 \)
- \( n \) is an integer.
**Example:**
- The number 3000 can be expressed as \( 3.0 \times 10^3 \).
- The number 0.0045 can be expressed as \( 4.5 \times 10^{-3} \).

### Section 2: Practice Problems
1. **Convert the following numbers to scientific notation:**
a. 5000
b. 0.00067
c. 1200000
d. 0.0032
2. **Convert the following scientific notation back to standard notation:**
a. \( 8.2 \times 10^4 \)
b. \( 3.1 \times 10^{-2} \)
c. \( 1.5 \times 10^6 \)
d. \( 7.5 \times 10^{-4} \)
3. **Perform the following operations (result in scientific notation):**
a. \( (3 \times 10^3) + (4 \times 10^3) \)
b. \( (2 \times 10^5) \times (3 \times 10^2) \)
c. \( (5 \times 10^{-3}) / (2 \times 10^{-1}) \)
