Answer:
$$?=10.$$
$$$$
Explanation:
Suppose that
we have an equilateral triangle $Delta rm ABC$:
Then,
the number in the middle of the triangle (say, $rm M$) is created from the formula: $$rm M = (Itimes II) + III - 10.$$
$$$$
Examples:
$$beginalign 33 &= (5times 7) + 8 - 10 \ &= 35 -2 \ &= 33;colorgreencheckmark tag1 endalign$$
$$beginalign 63 &= (7times 9) + 10 - 10 \ &= 63 + 0 \ &= 63;colorgreencheckmarktag2endalign$$
And last but not least...
$$beginalign132 &= (12times 11):+:? - 10 \ &= 132:+:? - 10 \ &= 122:+:? \ &Downarrow \ ?&=132-122 \ &= 10.tag3endalign$$

(+1) nice. As a challenge, seeing as you love mathjax perhaps you could try producing the triangle with it? ;)

Oh my... that is beautiful! But unfortunately, when I tried it, it does not work... Thus far, my best bet is the following: $$LARGEtriangle$$ Since it contains 'document' commands, I am pretty sure this can only be done when writing an actual document (paper) using $LaTeX$, but this theory is a little debunked because the user in the link can format it on the TeX site... perhaps Puzzling alone is culpable, because when I type it, there is an "unknown environment 'document'".

Alternative answer:
Pattern:
The fractional part of $fractextnumber in triangletextnumber left of triangle$ is less than $frac12$.
Hence the answer is
$10$
as
$$frac1327=18.85cdots,quadfrac1328=16.5,quadfrac1329=14.66cdots,quadfrac13210=13.2$$
Examples:
$$frac338=4.125,quadfrac6310=6.3$$
