Many mathematics majors go into teaching, either at high school level with a bachelor's (plus an education course) or at a college with further study. Banks, finance firms, and intelligence agencies (who spend a lot of money on breaking their opponents' codes) are also major employers.
Mathematicians are generally prized in many less obvious roles for their highly disciplined reasoning and problem-solving skills. Both the public and private sectors employ large numbers as data analysts, while knowledge of any other line of work leads to almost limitless career options. Math graduates are in very high demand and earn an average salary of $96,500 per year.
