Wolfram Alpha Launches Problem Generator To Help Students Learn Math

If you’re studying math or science, you are probably pretty familiar with Wolfram Alpha as a tool for figuring out complicated equations. That makes it a pretty good tool for cheating, but not necessarily for learning. Today, the Wolfram Alpha team is launching a new service for learners, the Wolfram Problem Generator, that turns the “computational knowledge engine” on its head.

The Problem Generator – which is available to all Wolfram Alpha Pro subscribers now – creates random practice questions for students, and Wolfram Alpha then helps them find the answers step-by-step.

Right now, the Generator covers six subjects: arithmetic, number theory, algebra, calculus, linear algebra and statistics. The difficulty of the questions can be tuned down for students in elementary school and tuned up for those in college calculus classes.

This $1,000 boondoggle has a curved face, and otherwise resembles a Galaxy Note, except with a $1,000 price tag. The screen seems to have little benefit beyond hugging a thigh better when ensconced in the pocket of jeans, or fitting the curve of a palm slightly more comfortably…
