# 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
