Good day,
I would like to extend my gratitude for the instructive session conducted
by Mr. Jonathan. His guidance was invaluable, and I've created materials
that may be beneficial to others who did not attend.
I am attaching 2 files, one is just some math written in LaTex, and the
other is a text file with explanations.
Best regards.

1. **Addition in LaTeX:**
   - LaTeX: `2 + 2 = 4`
   - Explanation: In LaTeX, you can simply use the plus sign (+) for addition, just like in regular mathematics.

2. **Multiplication in LaTeX:**
   - LaTeX: `2 \times 2 = 4`
   - Explanation: To denote multiplication in LaTeX, use the backslash (\) followed by the "times" symbol (\times).

3. **Exponents in LaTeX:**
   - LaTeX: `2^2 = 4`
   - Explanation: To represent exponents in LaTeX, use the caret (^) symbol followed by the exponent value. This example signifies 2 raised to the power of 2.

4. **Fraction in LaTeX:**
   - LaTeX: `\frac{1}{2} = 0.5`
   - Explanation: For fractions in LaTeX, use the `\frac` command and enclose the numerator and denominator in curly braces.

5. **Exponents with more than one digit in LaTeX:**
   - LaTeX: `2^{10} = 1024`
   - Explanation: When the exponent has multiple digits, enclose it in curly braces.

6. **Exponents with variables in LaTeX:**
   - LaTeX: `2^{x + 1}`
   - Explanation: LaTeX can represent exponents with variables just like constants. Use the caret (^) symbol, followed by the variable and its exponent.

7. **Python Exponents:**
   - Python: `2 ** 5 == 32`
   - Explanation: In Python, the double asterisk (**) operator is used for exponentiation. This example checks if 2 raised to the power of 5 equals 32.

8. **Subscripts in LaTeX:**
   - LaTeX: `P_1=(x_1, y_1)`
   - Explanation: Subscripts are indicated using an underscore (_) in LaTeX. Here, we define two points, P_1 and P_2.

9. **Slope Formula in LaTeX:**
   - LaTeX: `\frac{y_2 - y_1}{x_2 - x_1}`
   - Explanation: This is the formula for calculating the slope between two points. Subscripts are used for the coordinates, and the fraction is represented using `\frac`.

10. **LaTeX Fraction Format:**
    - LaTeX: 
      \frac{1}{x} = \frac{1}{x}
      \frac{1}{1+\frac{1}{x}} = \frac{x}{x+1}
    - Explanation: LaTeX allows you to represent fractions in a more readable format using `\frac`. The second example demonstrates nested fractions.
