    I am the main developer of the MathPiper CAS ( http://mathpiper.org ), and I forked it from the Yacas CAS in 2008. MathPiper is a rewriting system that is similar in design to Math…

    I am in the process of writing a step-by-step elementary algebra equation solver that solves these problems like a human does. One thing I have learned from this experience is a go…

    Doug Lenat (who started the Cyc project) says Cyc is the "last man standing" of the large logic-based AI projects. So I don't think any open-source projects that are similar to it …

    Cyc is used in the MathCraft application, which is currently in beta: http://www.cyc.com/mathcraft/ I don't think Google, Bing, Wolfram Alpha, or Siri can be used for applications …

    I spend 1-2 hours each day learning Cyc, and each day I see it do something new. For example, I just asked Cyc "Where did the 2012 Summer Olympics take place?" and this was its res…

    No currently used step-by-step equation software I am aware of shows all of the steps (inferences) that are needed to solve an equation, and why it took those steps. For example, I…
