I am just an end user like you. However, if you have created fields for these, you need to then create a function that uses those field IDs to calculate with. You can also add a button that updates the total if the user changes something with the fields. Bear in mind that your description above is pretty vague. I mean, I do not know if you’re using radio buttons or check boxes or what. If you are using something like radio buttons then your function to be written will have to be some sort of compound IF statement.

The formulas are just like those you use in MS Excel. They also follow the basic principle for mathematics which is Please Excuse My Dear Aunt Sally or Everything in parenthesis first, then exponents next, then multiplication, then division, then addition, then subtraction.

What that means is if I have the formula:

(2+4)*6 = 36
You add the 2 and the 4 first because they are in parenthesis, then you multiply that total by 6

If you had:
2+4*6= 26

You would multiply the 4 by the 6 giving you 24 and then add 2 to that giving you a total of 26

It is all in the order that you calculate.
Good luck.
