Four-function calculators-those that only perform addition, subtraction, multiplication, and division-gradually entered the classrooms, dividing educators and parents alike. Today, prices for graphing calculators hover around $80.īy the mid 1970s, 11 percent of Americans owned a calculator. (Kilby later won the Nobel Prize in physics.) A decade later, calculators would no longer be stored in gigantic cabinets with a price tag of over $700,000 they would substantially diminish in size and gradually become more affordable. Although the abacus has been in use since the time of the Sumerians and Ancient Egyptians, it wasn’t until 1958 when the Texas Instrument engineer Jack Kilby invented the integrated circuit, which paved the way for the cheap and compact computer chips used in most electronic devices today. The debate over the use of calculators in math classrooms has ensued for more than four decades-nearly as long as the contemporary calculator has been around. This isn’t an unusual predicament: According to a 2010 national survey by the Mathematical Association of America, nearly half of Calculus 1 college instructors prohibit students from using graphing calculators on exams.

When I took my freshman math courses at McGill University in Montreal last school year, I had to revert back to pencil and paper, clumsily lining up columns to do addition and long-multiplication problems at my professor’s request. Still, college professors remain divided on the use of calculators in their classes. Calculators are so commonplace in modern American education that a TI-84 or -89 can be found stashed away in many homes, mementos from taking the SAT or computing integrals on the Advanced Placement calculus exam. The Pi was created as a simple and inexpensive device to teach computer science and engineering and has become a favorite of the maker community, running everything from automated dog feeders to full-fledged web servers.Step inside any high-school math class in the United States, and chances are you’ll find students staring down at their Texas Instrument calculators, nimbly typing commands into those $100 pocket computers. With the Wolfram tools available on the Pi, Upton said it will be possible to give an entire class the tools needed to practice computer-based math for less than $1,000. “These are people who are really committed to this idea of trying to reform math education,” Upton says. With computers to help with calculations, teachers can be more focused on problem solving and less on mechanically applying formulas, the organization says. The summit was organized by, an organization founded by Wolfram Research executive Conrad Wolfram, the brother of Stephen Wolfram, to encourage the use of computers to teach math. Mathematica and Wolfram Language for the Pi were launched Thursday at the Computer-Based Math Education Summit at UNICEF’s New York headquarters. We’ve got a language that’s not mostly concerned with the details of computers, but is instead about being able to understand and create things on the basis of huge amounts of built-in computational ability and knowledge.

Wolfram Research founder Stephen Wolfram wrote in a blog post about the launch: Wolfram Alpha is Wolfram Research’s online “computational knowledge engine,” sort of a cross between a high-powered graphing calculator and an almanac of facts about the world, from physical constants to baseball scores, all of which will be accessible via Wolfram Language. The Pi is the first device to support the new language, which aims to provide a uniform, cross-platform interface to Mathematica’s core equation-solving and number-crunching functionality and to Wolfram Alpha. The Raspberry Pi launch is part of Wolfram Research’s efforts to make its new Wolfram Language–a programming language that expands on Mathematica’s existing command line interface–available across a wide range of devices, from low-powered embedded computers to cloud-based servers to parallel computing clusters. “It felt like the right one for the platform.” “I think in its class–symbolic computation program–I think it’s the best thing that’s available,” Raspberry Pi cofounder Eben Upton says of Mathematica.
