Calculator Skill

This skill performs basic arithmetic calculations.

When to Use

Use this skill when:

  • •The user asks to perform mathematical calculations
  • •Addition, subtraction, multiplication, or division is needed
  • •Numerical results need to be computed
  • •The user mentions terms like "calculate", "add", "subtract", "multiply", "divide", "sum", "difference", "product", or "quotient"

Instructions

  1. •

    Identify the operation the user wants to perform:

    • •Addition: combining two or more numbers
    • •Subtraction: finding the difference between numbers
    • •Multiplication: repeated addition or scaling
    • •Division: splitting into equal parts
  2. •

    Extract the numbers from the user's request

  3. •

    Perform the calculation:

    • •For addition: Add all numbers together
    • •For subtraction: Subtract the second number from the first
    • •For multiplication: Multiply the numbers together
    • •For division: Divide the first number by the second
  4. •

    Handle edge cases:

    • •Division by zero: Return an error stating "Division by zero is not allowed"
    • •Very large numbers: Use appropriate precision
    • •Decimal numbers: Maintain precision to at least 2 decimal places
  5. •

    Present the result clearly with the operation performed

Examples

Example 1: Addition

Input: "What is 15 + 27?" Steps:

  1. •Operation: Addition
  2. •Numbers: 15 and 27
  3. •Calculation: 15 + 27 = 42 Output: "The sum of 15 and 27 is 42"

Example 2: Division

Input: "Divide 100 by 4" Steps:

  1. •Operation: Division
  2. •Numbers: 100 and 4
  3. •Calculation: 100 ÷ 4 = 25 Output: "100 divided by 4 equals 25"

Example 3: Multiplication with decimals

Input: "Calculate 3.5 times 8" Steps:

  1. •Operation: Multiplication
  2. •Numbers: 3.5 and 8
  3. •Calculation: 3.5 × 8 = 28 Output: "3.5 multiplied by 8 equals 28"

Example 4: Division by zero (error case)

Input: "What is 10 divided by 0?" Steps:

  1. •Operation: Division
  2. •Numbers: 10 and 0
  3. •Detect division by zero Output: "Error: Division by zero is not allowed. Please provide a non-zero divisor."

Common Edge Cases

  • •Division by zero: Always check if the divisor is zero before performing division
  • •Negative numbers: Handle negative results appropriately
  • •Decimal precision: Round results to a reasonable number of decimal places (typically 2-4)
  • •Very large numbers: Be aware of potential overflow issues
  • •Multiple operations: If the user requests multiple operations, perform them in the correct order (following PEMDAS/BODMAS if applicable)

Tips

  • •Always confirm the operation and numbers with the user if ambiguous
  • •Show your work when helpful for understanding
  • •Use clear mathematical notation in your response
  • •For complex expressions, break them down into simpler steps
