- Rapid Specialization: Quick task-specific performance
🔍 Example: Mathematical Reasoning
Problem: "A restaurant has 15 tables. Each table can seat 6 people. If the restaurant is 80% full, how many people are currently seated?"
Step 1: Calculate total capacity
Total seats = 15 tables × 6 people per table = 90 people
Total seats = 15 tables × 6 people per table = 90 people
Step 2: Apply occupancy rate
Current occupancy = 90 × 80% = 90 × 0.8 = 72 people
Current occupancy = 90 × 80% = 90 × 0.8 = 72 people
Step 3: Provide final answer
Therefore, 72 people are currently seated in the restaurant.
Therefore, 72 people are currently seated in the restaurant.
