An Online Experience
As more of our jobs, events and data continue to shift online, so must our innovation. To reflect our increasingly virtual world, the 2021 Raytheon Technologies MATHCOUNTS National Competition celebrated the fields of cybersecurity and computer science—and the crucially important role of mathematics in advancing them.
From encrypting information and deciphering codes to creating algorithms and computer programs, mathematics is the basis of the virtual world. When we help young thinkers fine-tune their math skills, we help inspire the problem-solvers of tomorrow.
