Wolfram|Alpha Notebook Edition combines the simplicity of Wolfram|Alpha with the computational capabilities of Mathematica for the best of both in a single, unified tool perfect for teaching and learning. Use free-form input to get instant answers to questions, create and customise graphs, and turn static examples into dynamic models. Everything is saved as an interactive Wolfram Notebook, so you can add notes and use notebooks as class or reference materials, or present them as dynamic slide shows that engage your audience as you edit examples on the fly.
