How to add values ​​of two selects in angular.js?

Question

css

Do not scold too much, I took up angular, so to speak, in order to feel the benefits on a mini-task (as they say).
And so we have select. The data is stored in an array. When selected, the price for each item is immediately displayed.
But now you need to add more additional options to the product and sum up the price of a particular product with the price of additional options
. Product1 = 500 + additional option 200 and should output 700 as a result.
How to count elements of different selects?
