In a future not so far way, Earth archaeologists find on a far away planet a fragment from a long lost civilization.
This fragment involves an unknown operation *|*.
Unlocking its secrets may lead to a breakthrough in understanding their civilization.

Can you do it?

If
21 *|* 7 = 11
and
17924 *|* 10751 = 851
then how much is:
1982 *|* 2010 = ?

:P let's just say they were a little more advanced and the operation is not that simple.
Nice thought though, I did not see that one (just chose a small example at random).

Spoiler for Hint(s)

Indeed, your operation works for the given examples. I like it :D

It's not however the *|* that I had in mind (it gives a different result to the question).
Nonetheless, it deserves a prize as a valid hypothesis.

Perhaps a new example can re-launch the challenge?
Give me a pair (a,b) and I'll compute a*|*b. (i.e. assume another tablet has been found on the planet, etc, to maintain the "cover story" :D).

Knew it was a little too convoluted. Would have thought it much easier to find several cases that satisfied the operation given only two data points. And tried many many different approaches. A tribute to a well thought out challenge. Will be looking for another tablet as well as continuing analyzing what we've found thus far.

Adding another example to the challenge. Same operation as before.

1089 *|* 121 = 2069
