==Explanation==&lt;br /&gt;
{{incomplete|This page was created recently. Don't remove this notice too soon.}}&lt;br /&gt;
&lt;br /&gt;
A {{w|dental formula}} specifies the number of teeth of each type on each side of the jaw, with dots separating the numbers. There are two rows, representing the upper and lower jaw, separated by a horizontal line. The number of incisors is indicated first, canines second, premolars third, and finally molars, so the formula in the comic would represent 3 incisors, 1 canine, 3 premolars, and 1 molar on each side of the upper jaw, and equal numbers in the lower jaw except only 2 premolars.&lt;br /&gt;
&lt;br /&gt;
Cueball is (wrongly) treating a dental formula as an arithmetic expression, with the line indicating division.&lt;br /&gt;

Do mammatologists think these are hard?&lt;br /&gt;
I mean this one just evaluates to 3/2.&lt;br /&gt;

Mathematicians encounter dental formulas&lt;br /&gt;
