数学的研究是由于其广泛的适用性和内在的美。数学理论通常是源于物理和生物科学，工程，经济学，金融和社会科学中出现的问题。应用程序经常使用为完全不同的目的而创建的数学。威廉和玛丽的数学课程允许学生根据自己的兴趣和职业目标设计专业，并为学生做好学业后的就业准备以及进一步学习数学科学和相关学科的准备。在主要–标准集中，应用数学集中和大学预科数学教学集中有3个集中。学习选择包括应用数学和纯数学，运筹学，统计学和小学或中学水平的教学。学生还可以设计精算科学和工业数学职业，经济学，商业和社会科学等领域的跨学科工作或研究
Mathematics is essential in many fields, including natural sciences, engineering, medicine, finance, computer science and social sciences. Some areas of mathematics, such as statistics and game theory, are developed in close correlation with their applications and are often grouped under applied mathematics. Study options include applied and standard mathematics, operations research, statistics and actuarial science.<br>Graduate students focus their studies on computational operations research, a program administered by the Department of Computer Science.<br>The mathematics program at William & Mary allows you to design a major based on your own interests and career goals. You will be prepared for employment and for further study of mathematical sciences and related disciplines.<br>The Mathematics Department offers three concentrations within the major:<br>Applied Mathematics Concentration<br>Mathematics and its applications have always been intertwined. Geometry developed in support of the great civil engineering projects of Egypt and Greece. At least since the time of Newton, physical science and mathematics developed in tandem. Other disciplines have become increasingly mathematical. To a large degree, economics and finance are now the study of specialized mathematical models. The social sciences use game theory, probability, and statistics as the organizing tools for much of their research. Modern industry uses the insights of operations research to achieve prosperous levels of efficiency. Modern biology uses differential equations to study population growth, predator-prey interactions, and the inner workings of cells. These applications, coupled with remarkable advances in computing, have created whole new fields of mathematics.<br><br>The applied mathematics concentration is designed for students who want to pursue applications of mathematics or to double major in mathematics and another discipline. Students who plan to seek employment immediately after graduating and who want to develop specific skills may be well served by the applied track.<br><br>Students who plan to pursue graduate study in applied mathematics may be better served by acquiring a strong background in the fundamental branches of modern mathematics via the standard concentration track.<br><br>The requirements for the applied mathematics concentration allow for a great deal of flexibility. Students develop their own program of study in consultation with their major advisor.
