Our Story

Math is beautiful and tremendously powerful in the hands of experts. On the other hand, to novices, math is frustrating and HARD....All those rules to memorize. All those steps to write and keep track of.

In a world where technology has advanced at astonishing rates, the technology of math notation hasn’t really changed in 400 years. The easiest way to write and solve an equation is still by hand, on paper.

For a few years, a group of us—math educators, psychologists, mathematicians, and computer scientists—have been imagining ways to reconstruct the idea of formal notation by using digital technology. We think it’s time to apply modern design approaches to build more intuitive and fluid interfaces for math. We want tools that scaffold experiences of algebraic structure, support genuine inquiry about how math works, and give people opportunities to reason flexibly about mathematics.

The Team

David Landy
David Landy is an adjunct professor at Indiana University Bloomington. His academic research focuses on the cognitive mechanisms behind mathematical thinking. David wants to see static math expressions replaced by interactive ones everywhere to change how we learn, use, and share math.
Erik Weitnauer
Erik Weitnauer is an entrepreneur and software developer (and German Math Olympics finalist back in 12th grade). He believes in changing the world through education and is developing Graspable Math to help students learn algebra in a more intuitive way.
Erin Ottmar
Erin Ottmar is a professor of learning sciences, technology, and psychology at the Worcester Polytechnic Institute, focusing on math teaching and learning. She has been a teacher herself and is passionate about studying the impact of interactive math notations on children and teachers.
