Are there any in-depth docs for the calculation field?

I am trying to build a form that calculates the amount of two fields and then adds on a fixed amount and then passes this info to Paypal.

Here are the details.
We have lodges that pay dues of $6.00 a year per member.
I need to understand how to use the calculation field to add one field that varies - the number of members
then multiply that amount by $6.00, which is a fixed amount not editable on the user end of the form.
This amount then adds another fixed amount say $2.00 for a processing fee and then this total gets handed over to Paypal.

I have been looking for docs to understand how to do this but I've been unable to locate any.

Help in doing this would be greatly appreciated.

Would the cart field be better to use for this?

Hello,
Thank you for contacting us

You can use any mathematical functions
developer.mozilla.org/en-US/docs/Web/Jav.../Global_Objects/Math

In the settings of the calculation field, set “product”
and add cart.
In the settings of the send button, select the payment system (which was configured in integrations)
