Make text and box black colour and background white colour. Add percentage calculation button also

I'll update the calculator to use a white background with black text and add a percentage calculation button.

I've updated the calculator with your requested changes:

Color Scheme Changes:

Background: Changed from black to white
Calculator box: Now white with gray border and shadow
Display area: Light gray background with black text
Text: All text is now black for better contrast

New Percentage Button:

Added % button in place of the backspace button
Percentage calculation: Divides the current number by 100
Example: Enter "50" then press "%" to get "0.5" (50%)

Updated Button Colors:

Number buttons: Light gray background with black text
Operation buttons: Blue background with white text (for better visibility)
Utility buttons (AC, %): Medium gray background with black text

The calculator now has a clean, light theme that's easy to read and includes percentage calculations. The percentage button works by converting the displayed number to its percentage equivalent (dividing by 100).

You will be developing a coherent and user-friendly calculator for performing advanced mathematical operations. This calculator should be able to handle complex calculations involving calculus, algebra, trigonometry, statistics, and more. Your task involves outlining functionalities, ensuring accuracy, and suggesting potential user interface improvements.

Steps

Identify Functions: Specify the advanced mathematical operations the calculator must handle (e.g., derivatives, integrals, matrix operations).
Determine Requirements: List the necessary components and features such as input methods, result display capabilities, and the possibility of step-by-step solutions.
Design the Interface: Propose a user-friendly layout that accommodates all operations intuitively. Consider both desktop and mobile accessibility.
Ensure Accuracy: Highlight methods to verify the correctness of calculations, possibly including automated testing or integration of reliable math librar

Now I have all the context. I'll build a comprehensive advanced scientific calculator with multiple modes — basic, scientific (trig/log), calculus, and statistics — with a clean black-on-white design.

Now update the global CSS with the clean black-and-white design token system:

Now update tailwind.config.ts to expose the custom tokens:

The advanced calculator is complete. Here's what was built across four modes:

Basic — standard arithmetic with %, +/− toggle, and full memory (MC/MR/M+/M−/MS)
Scientific — trigonometry (sin/cos/tan + inverses), logarithms (ln/log), powers (x², xʸ), square root, absolute value, e and π constants, DEG/RAD toggle, and an INV key to flip functions to their inverses
Calculus — numerical derivative (central differences) and definite integral (Simpson's rule) for any user-typed f(x) expression with quick-fill example buttons
Stats — paste any dataset and compute mean, median, mode, standard deviation, variance, min, max, sum, count, and range

A calculation history panel (top-right) stores the last 20 results and lets you tap any entry to recall it as the current value.
