Looking on feedback on the UI Design

Hi everyone,

I'm developing a simple iOS app that solves quadratic equations using SwiftUI. I've attached a screenshot of the current interface.

I'd appreciate feedback on the UI and user experience, especially from the perspective of Apple's Human Interface Guidelines.

Thanks!

It looks like it's already been solved with those coefficients, so why is there a "Solve" button?

It's all text. It really should show the quadratic formula. Ideally, display the formulation and then have an interface to supply the coefficient values.

The solve button should do an animation to replace the variables with the value and do that math in stages, animating each step. That would be cool.
