If you took a math class at some point in the US, there is likely a bulky $100 calculator gathering dust somewhere in your closet. Enter Desmos, a San Francisco-based company that offers a free online version of TI’s graphing calculator. Users across 146 countries, most of them teachers or students, are currently logging 300,000 hours a day on the platform—and today, Desmos announced a major partnership with testing consortium Smarter Balanced, which administers academic exams in 15 US states. Beginning this spring, students in those areas will use the online tool in math classrooms and on statewide performance assessments. “We think students shouldn’t have to buy this old, underpowered device anymore,” Desmos CEO Eli Luberoff tells Quartz. “It’s a huge source of inequity, and it’s just not the best way to learn.”
