Students usually find easy access to several campus computer labs, including mainframe, mini, and microcomputers. Students are active in the Math Club, which meets weekly and sponsors various activities and talks.

Endowments honoring Michael Tucker and Harry Kieval enable the mathematics department to award a total of $2500 in scholarships to two or three outstanding math majors each year. The Harry S. Kieval endowment also provides for guest lecturers twice each year and for an annual scholarship ($300 per student) for one or two students transferring to Humboldt State University with the intention of majoring in mathematics. Potential careers include: systems analyst, teacher, statistics methods analyst, demographer, economic analyst, mathematics consultant, statistician, applied science programmer, financial investment analyst, actuary, and mathematician.

Degrees offered at HSU include:

- Bachelor of Arts degree with a major in Mathematics option available in applied mathematics
- Minor in Mathematics
- Minor in Applied Mathematics
- College Faculty Preparation Program: Mathematics
