The expression extracted from the image is:

$5 \times 5 + \frac{5}{3} \times \frac{10}{5} + \frac{30}{2} \times 4 - 100$

Let's simplify and calculate it step by step:

1. $5 \times 5 = 25$
2. $\frac{5}{3} \times \frac{10}{5} = 1 \times 2 = 2$
3. $\frac{30}{2} \times 4 = 15 \times 4 = 60$
4. Now combine all the results: $25 + 2 + 60 - 100 = -13$

Thus, the final result of the expression is $-13$.

Would you like more details on any step? Here are some follow-up questions for further practice:

1. What is the effect of changing the subtraction to addition in the expression?
2. Can you write a similar expression but with exponents?
3. How does changing the order of operations (using parentheses) affect the result?
4. What happens if one of the fractions is inverted, such as $\frac{3}{5}$ instead of $\frac{5}{3}$?
5. How would you evaluate the same expression using decimals instead of fractions?

Tip: Always follow the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) to get correct results.
