UpStudy AI · Accepted Answer

Let's evaluate the expression step by step:

$$ (20 + (2.5 \times 3)) - 3^{3} $$

1. **Calculate the multiplication inside the first parentheses:**
   $$
   2.5 \times 3 = 7.5
   $$

2. **Add the result to 20:**
   $$
   20 + 7.5 = 27.5
   $$

3. **Calculate the exponentiation:**
   $$
   3^{3} = 3 \times 3 \times 3 = 27
   $$

4. **Subtract the exponentiation result from the sum:**
   $$
   27.5 - 27 = 0.5
   $$

**Final Answer:**
$$
0.5
$$
The final answer is 0.5.
