This Casio graphing calculator tool helps you solve complex mathematical problems with ease.

## How to Use the Calculator:

To use this calculator, simply input a mathematical expression into the “Enter Expression” field. This can include basic arithmetic operations like addition (+), subtraction (-), multiplication (*), and division (/). You can also use parentheses to dictate the order of operations.

## How it Calculates the Results:

When you input an expression and press the “Calculate” button, the calculator will evaluate the expression using standard JavaScript functions. The result will be displayed in the disabled “Result” field.

## Limitations:

Please note that this calculator has limitations:

- It does not support advanced mathematical functions like trigonometry, logarithms, or exponents.
- It performs evaluations using JavaScript’s
`eval()`

function, which means it may not handle complex calculations accurately. - It cannot handle variables or functions; it only evaluates static expressions.
