Making an info form

newbie alert!!
I am trying to build a form page. Along with the text input fields, I also need to use some components but never have before and don’t know a thing about them. I need to make a menu button that has numbers 1-10. This number then is to multiplied by a another and the sum needs to be displayed in another box on the form. Then then when the user pushes “send” I need to receive this info. I think is will use both input and dynamic text fields, but I’m totally lost.

Thanks for your help.
