# Calculator

**Calculator** enables an Agent to perform mathematical calculations.

## Example

The following agent will calculate the result of `10*5` and then raise it to the power of `2`:

```python cookbook/tools/calculator_tools.py theme={null}
from phi.agent import Agent
from phi.tools.calculator import Calculator

agent = Agent(
    tools=[
        Calculator(
            add=True,
            subtract=True,
            multiply=True,
            divide=True,
            exponentiate=True,
            factorial=True,
            is_prime=True,
            square_root=True,
        )
    ],
    show_tool_calls=True,
    markdown=True,
)
agent.print_response("What is 10*5 then to the power of 2, do it step by step")
```

## Toolkit Functions

| Function       | Description                                                                              |
| -------------- | ---------------------------------------------------------------------------------------- |
| `add`          | Adds two numbers and returns the result.                                                 |
| `subtract`     | Subtracts the second number from the first and returns the result.                       |
| `multiply`     | Multiplies two numbers and returns the result.                                           |
| `divide`       | Divides the first number by the second and returns the result. Handles division by zero. |
| `exponentiate` | Raises the first number to the power of the second number and returns the result.        |
| `factorial`    | Calculates the factorial of a number and returns the result. Handles negative numbers.   |
| `is_prime`     | Checks if a number is prime and returns the result.                                      |
| `square_root`  | Calculates the square root of a number and returns the result. Handles negative numbers. |
