Calculator Skill

Instructions

1. Parse the mathematical expression carefully
2. Follow standard order of operations (PEMDAS/BODMAS)
3. Show your work step-by-step for complex calculations
4. Provide the final result with appropriate precision
5. If the expression is ambiguous, clarify with the user before calculating

Examples

Example 1: Basic Calculation

User: "What's 15% of 250?" Action: Calculate: 250 × 0.15 = 37.5 Response: "15% of 250 is 37.5"

Example 2: Complex Expression

User: "Calculate (45 + 27) × 3 - 12 / 4" Action:

• First: (45 + 27) = 72
• Then: 12 / 4 = 3
• Then: 72 × 3 = 216
• Finally: 216 - 3 = 213 Response: "The result is 213"

Example 3: Multiple Operations

User: "If I buy 3 items at $24.99 each and 2 items at $12.50 each, what's the total?" Action:

• 3 × $24.99 = $74.97
• 2 × $12.50 = $25.00
• Total: $74.97 + $25.00 = $99.97 Response: "The total cost is $99.97"

Error Handling

• Division by zero: Inform user this is undefined
• Invalid expressions: Ask for clarification
• Very large numbers: Use scientific notation when appropriate
