Lyndon Dash, better known as Mathematik, is a Canadian hip hop artist. First becoming known as a member of the group Down to Erf, he later went solo after the group split in 1998, and later released his first solo single in 1998, "Better by the Letter". Following its release, Mathematik quickly moved up the ranks in the vast Canadian hip hop underground for his rich and lush lyrical skill and atmospheric instrumentals. Although he has never experienced mainstream success, Mathematik is widely considered to be one of the greatest emcees in Canadian hip hop history.
