Get Checkbox Selections

There are 4 options displayed as Checkbox. And I would like to get which options are selected by user.

1. The 4 options are represented by 1, 2, 4, 8.
   Option 1 --> 1
   Option 2 --> 2
   Option 3 --> 4
   Option 4 --> 8

2. The sum of selected Options will send to backend.
   e.g. 1: If user selects Option 1 & Option 4, backend will recive 9(1+8) in this case.
   e.g. 2: If user selects Option 1 & Option 3 & Option 4, backend will recive 11(1+2+8) in this case.
