The given expression is $3(3 - 8)$.

Let's simplify it step by step:

1. Apply the distributive property, which means multiplying the number outside the parentheses by each term inside the parentheses: $3(3 - 8) = 3 \times 3 - 3 \times 8$

2. Perform the multiplication: $3 \times 3 = 9 \quad \text{and} \quad 3 \times 8 = 24$

3. Now, subtract: $9 - 24 = -15$

Thus, the simplified expression is $-15$.
