While searching for a way to represent advanced equations within MIT App Inventor, I couldn't find anything.
So, taking inspiration from:

Cree mi versión usando MathJax, el archivo .aia es el siguiente:
Maths.aia (275.5 KB)

It works very simply: you type inside the text box and the equation appears in the WebViewer; it must use LaTeX format.

If you want to add it to your application, you only need the "maths.html" and "tex-chtml.js" files.

Also, refresh the Web Viewer before inserting a new equation; an error occurs that prevents it from being displayed.

I did see that extension, but my purpose isn't to solve the equations, just to have a way to represent them in a way that's visually appealing. :grinning:

It's a good extension, but many of us can't afford it, and since I couldn't find an alternative, I decided to create one and share it.
