A professional society since 1888, we advance research and connect the diverse global mathematical community through publications, meetings and conferences, MathSciNet, professional services, advocacy, and awareness programs.

The Mathematical Association of America is the world’s largest community of mathematicians, students, and enthusiasts.
Our members include university, college, and high school teachers; graduate and undergraduate students; pure and applied mathematicians; computer scientists; statisticians; STEM professionals, and many others in academia, government, business, and industry. We welcome all who are interested in the mathematical sciences.

Society for Industrial and Applied Mathematics (SIAM) is an international community of over 14,000 individual members. Almost 500 academic, manufacturing, research and development, service and consulting organizations, government, and military organizations worldwide are institutional members.

Over 1,000 teachers and teacher educators belong to AMTE. We welcome anyone interested in the preparation of teachers of K-12 mathematics.

Founded in 1920, the National Council of Teachers of Mathematics (NCTM) is the world's largest mathematics education organization throughout the United States and Canada.
