How it works: Think of this application as a three-step translation process that turns a math problem into a beautiful result:

• The Interpreter: When you click the buttons, the app uses a library called MathQuill. This acts like a digital pen, allowing you to “write” complex equations (like fractions and square roots) so they look like real math on your screen instead of messy computer code.

• The Translator: Computers don’t naturally “read” math symbols the way humans do. I wrote a custom “Parser” function that acts as a translator. It takes your visual equation and instantly converts it into a language the computer’s brain can understand.

• The Brain & The Artist: Once translated, a powerful engine called Math.js does the heavy lifting—calculating the derivatives or integrals in milliseconds. Finally, KaTeX steps in like an artist to format that answer back into a clean, professional mathematical display.
