Not Sweating the Small Stuff

To Dunce Or Not To Dunce, That Is The Question

Ok guys, if the puzzle below takes more than a nanosecond (or three, let's not be too mean or anal), please insinuate yourself into a context similar to the one above, attired in the very same manner.

If ...

2 + 3 = 10

7 + 2 = 63

6 + 5 = 66

8 + 4 = 96

Then ...

9 + 7 = ?

Okay, so precisely where are you now after doing that, and what exactly are you wearing?

Of course, feel free to share any more 'exotic' locations you may be heading for ... if not required in the classroom!
