*Who Wants to Be a Mathematician* would not be possible without the continued support of our co-sponsors, Maplesoft and DigitalEd, Art of Problem Solving, Wolfram Research, The Good Thinking Society, the Pacific Institute for Mathematical Sciences (PIMS), Texas Instruments, and John Wiley & Sons, who donate the following:

Maplesoft™ and DigitalEd are our *Technology Sponsors*. They host online qualification tests for the *Who Wants to be a Mathematician Championship* contest with their online courseware, testing and assessment systems, Möbius Courseware and Möbius Assessment. Thanks to Maplesoft, the test moved to digital tests from the pen-and-paper format. DigitalEd now hosts online testing. In addition, Maplesoft donates the latest version of its software, currently Maple 2018, to the second-place winner in *Who Wants to Be a Mathematician* and co-sponsors a contestant from Canada. DigitalEd's **Heather Zunic** says, "As a leading provider of high-performance software tools for engineering, science, and mathematics, it is our pleasure to support high-school students who are enthusiastic about these fields." In the video below, Heather's colleague, **Louise Krmpotic**, talks to contestants and their parents at the 2018 Championship in San Diego.

Art of Problem Solving (AoPS) is the *Online Community Sponsor* of *Who Wants to Be a Mathematician*, and provides gift certificates to all participating schools. Visit the *Who Wants to Be a Mathematician* discussion forum on AoPS. Since 2003, AoPS has developed a wide range of educational materials for outstanding K-12 math students. Its online community at aops.com has over 350,000 members and hundreds of thousands of visitors each month. AoPS's textbooks have been used by tens of thousands of students, including many winners of major math national contests, and its online school serves thousands of students each year with courses in middle school and high school math, contest preparation, and computer science. AoPS's Beast Academy offers a complete, rigorous math curriculum for grades 2-5, and in 2016, AoPS Academy opened its doors, bringing the depth and rigor of the AoPS curriculum to the classroom. Below, AoPS's CEO, **Richard Rusczyk**, welcomes and congratulates the contestants in the 2018 *Who Wants to Be a Mathematician Championship*.

Wolfram, creator of Mathematica, Wolfram|Alpha and the Wolfram Language, is one of the world's most respected software companies. A pioneer in mathematical computation and modern data science, Wolfram pursues a long-term vision to research and develop the tools to make computation an ever-more-potent force for generations to come. Wolfram technologies are widely used in education, and the company actively promotes computational thinking through its Wolfram High School Summer Camp, along with the freely available Wolfram Challenges and Wolfram|Alpha websites for problem solving and education. Wolfram Research donates one-year licenses to Mathematica, Wolfram Programming Lab, and Wolfram|Alpha Pro to each student who takes the *Who Wants to be a Mathematician* qualifying test and successfully completes three Wolfram Challenges.

The Good Thinking Society is a registered charity in the UK, whose aim is to encourage curiosity and promote rational thinking. The charity works to promote science and mathematics education, and to challenge pseudoscience. Good Thinking organizes the UK leg of *Who Wants to Be a Mathematician*, as well as the Parallelogram weekly series of maths challenges and the Top-Top Set Maths Project, which seeks to challenge the most able mathematicians in secondary schools.

The Pacific Institute for the Mathematical Sciences (PIMS) co-sponsors a contestant from Canada in the annual game at the Joint Mathematics Meetings. The institute represents mathematicians from Alberta, British Columbia, Washington State, Saskatchewan, and Manitoba. The institute's mandate is to promote research in and applications of the mathematical sciences, to facilitate the training of highly qualified personnel, to enrich public awareness of and education in the mathematical sciences, and to create mathematical partnerships with similar organizations in other countries (with a particular focus on the Pacific Rim).

Texas Instruments donates a TI-Nspire graphing calculator, the TI-Nspire CX, to each winner of *Who Wants to Be a Mathematician*.

Each third-place finisher in *Who Wants to Be a Mathematician* receives a copy of *Calculus with Early Transcendentals*, written by Anton, Bivens, and Davis and donated by John Wiley & Sons.
