How to create a pricing calculator with Wappler?

I want to create a bootstrap form with sliders/number input/dropdown menus. When a user input those parameters, the form output a number that is a calculation of the user’s input.

Right now, I know how to create database queries and update database, but how do I implement a calculator? What are some ways to do this?

Thanks!

I assume we need to know perhaps how to implement a simple function in the PHP language?

There are a number of threads which may be useful, eg this one. No PHP needed.
