# Calculator Utilities A basic calculator utility that provides fundamental arithmetic operations via a Python script. ## How to Use Run the calculator script with an operation and numbers: ```bash python scripts/calculator.py <operation> <numbers...> ``` ## Operations ### Add Adds all numbers together. ```bash python scripts/calculator.py add 5 3 # Output: 8 python scripts/calculator.py add 10 20 30 # Output: 60 ``` ### Subtract Subtracts all subsequent numbers from the first number. ```bash python scripts/calculator.py subtract 10 4 # Output: 6 python scripts/calculator.py subtract 100 25 15 # Output: 60 ``` ### Multiply Multiplies all numbers together. ```bash python scripts/calculator.py multiply 6 7 # Output: 42 python scripts/calculator.py multiply 2 3 4 # Output: 24 ``` ### Divide Divides the first number by all subsequent numbers. ```bash python scripts/calculator.py divide 20 4 # Output: 5.0 python scripts/calculator.py divide 100 2 5 # Output: 10.0 ``` ## Error Handling - **Division by zero**: Returns an error message - **Invalid input**: Non-numeric values will show an error - **Missing arguments**: Shows usage instructions ## Examples ```bash # Simple addition python scripts/calculator.py add 100 50 # Output: 150 # Chain subtraction python scripts/calculator.py subtract 1000 250 150 100 # Output: 500 # Multiply decimals python scripts/calculator.py multiply 3.14 2 # Output: 6.28 # Division with decimals python scripts/calculator.py divide 22 7 # Output: 3.142857142857143 ```
