数学是一种神奇而美丽的智力创造，是人类最深切的努力之一。我们周围的世界和我们正在创造的未来世界是由数学编织而成的，从纳瓦霍人编织的对称群到飞鸟翅膀周围的气流以及全球计算机网络的安全性。数学无处不在。达特茅斯大学的数学系是学习和研究未解决的问题和弯腰概念的地方。数学专业不仅适用于计划数学和相关领域职业的学生，​​也适用于那些仅对数学感兴趣的学生。专业的内容是灵活的，可以选择课程以反映学生的兴趣。数学专业的学生将有机会通过小型研讨会和独立研究项目与教师紧密合作。
The major in mathematics is intended both for students who plan careers in mathematics and related fields, and for those who simply find mathematics interesting and wish to continue its study. The content of the major is quite flexible, and courses may be selected largely to reflect student interests. Students who major in mathematics have an opportunity to participate in activities that bring them in close contact with a faculty memberfor example, through a small seminar or through an independent research project under the direction of a faculty member. In addition to regular course offerings, a student with specialized interests, not reflected in our current course offerings, often arranges for an independent reading course. Proposals for independent activities should be directed to the Departmental Advisor to Mathematics Majors.<br>In general, the mathematics major requires the student to pass eight mathematics or computer science courses beyond prerequisites. At least six of the required eight courses must be mathematics, and at least four of these courses must be taken at Dartmouth. In addition, a student must fulfill the College's requirement for a culminating experience in the major (see below). Additional requirements for honors are described below in a separate section.
