Another way of asking a person for their number. Based on the holla holla holla guy from dave chappelle's show.

Explanation of phrase: when one asks for another persons number they usually say it by "can i have your number?" or "I see that fine bootay of yo's, holla with them digits at meh why dontchya?" The reason we say "mathematics" is because a number is theoretically math, hence the term can i have yo mathematics?
