## How It Calculates Results

This calculator uses JavaScript’s `eval()`

function to evaluate the string of arithmetic operations you input. It processes the operations in the standard order of arithmetic operations (PEMDAS/BODMAS rules).

## Limitations

While this simple calculator can handle basic arithmetic operations, it has a few limitations:

- It cannot handle complex expressions involving parentheses or advanced mathematical functions.
- The
`eval()`

function may not handle invalid input gracefully, so ensure you enter a valid arithmetic expression. - Division by zero will result in an error.

For more advanced calculations, consider using a more sophisticated calculator or a mathematical software application.
