Calculator

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
