**Step-2: Using On-Screen Buttons**

Use the on-screen buttons for common mathematical functions and symbols:

**Basic Operations:**+, -, *, /**Trigonometric Functions:**sin(), cos(), tan(), asin(), acos(), atan()**Constants:**π, e**Exponentiation:**^, x², x³, exp(), 10^**Roots and Logarithms:**sqrt(), cbrt(), √(), log()**Factorial:**fact()**Miscellaneous:**(, ), 1/, %, ±

**Step-3: Evaluate the Expression**

After entering the expression, press the '=' button on the calculator or press 'Enter' on your keyboard to evaluate the expression.

**Step-4: View the Result**

The result of the evaluated expression will be displayed below the input field. If there is an error in the expression, an error message will be displayed instead.

**Step-5: Clear or Edit the Expression**

Use the 'AC' button to clear the entire input field or the 'Del' button to delete the last character or scientific function in the expression. You can also edit the expression directly in the input field.

**Step-6: Additional Functions**

Use the 'Ans' button to use the last calculated result in a new expression, and the '±' button to toggle the sign of the current input.

**Step-7: Customization and Preferences**

You can adjust your input and calculation preferences as needed. The calculator will remember your current state for seamless calculation continuity.
