I'm not sure what these numbers are referring to, i.e. the 79, 11, 11, 1, 1.
These numbers are your current reputation score in each of these Stack Exchange communities.
Currently you have 79 on Stack Overflow, 11 of Electrical Engineering, 11 on Motor Vehicle Maintenance & Repair, 1 on Aviation, and 1 on Meta. (Also 1 on Physics, but that dropdown menu will only show your top 5 sites.)
The numbers displayed in that dropdown menu will change as your actual reputation score on the various sites changes.
