October 18, 2013
We are proud to announce Wolfram Problem Generator, a website where students decide which topic they want to practice and we provide the questions and solutions. This is an exciting new way to help students with their classes: previously, students provided their own practice questions and Wolfram|Alpha helped them find answers with Step-by-step solutions. Students can now ask Wolfram|Alpha for help with practice and homework questions and can do practice problems with Wolfram Problem Generator.
Currently, there are six main topics that Wolfram Problem Generator covers: arithmetic, number theory, algebra, calculus, linear algebra, and statistics. The topics range from early elementary school all the way through college calculus. Moreover, for elementary and secondary education material, we are closely following the Common Core Standards initiative to provide a comprehensive list of topics.
The monthly subscription cost for Wolfram Alpha Pro is $5/month. Our family has not tried it yet. Wolfram created Mathematica.
