In other news, world's high school math teachers declare Wolfram Alpha, "dead to us."
Have you ever given up working on a math problem because you couldn't figure out the next step? Wolfram|Alpha can guide you step by step through the process of solving many mathematical problems, from solving a simple quadratic equation to taking the integral of a complex function.
[For example] When trying to find the roots of 3×2+x-7=4x, Wolfram|Alpha can break down the steps for you if you click the "Show steps" button in the Result pod.
