UpStudy AI · Accepted Answer

1. **Evaluate the innermost parentheses:**

- Calculate $$ 28 \div 4 $$:
     $$
     28 \div 4 = 7
     $$
   - Calculate $$ 25 - 20 $$:
     $$
     25 - 20 = 5
     $$

2. **Multiply the results inside the square brackets:**

- Multiply $$ 7 $$ by $$ 5 $$:
     $$
     7 \times 5 = 35
     $$

3. **Add the result to the 3 inside the curly braces:**

- Add $$ 3 $$ and $$ 35 $$:
     $$
     3 + 35 = 38
     $$

4. **Multiply by 4:**

- Multiply $$ 4 $$ by $$ 38 $$:
     $$
     4 \times 38 = 152
     $$

The final answer is $$ 152 $$.
The final answer is 152.
