Wolfram Alpha is a computational search engine that calculates answers to inquiries rather than just providing websites. It offers features like uploading images, data, or files to get additional information beyond traditional search engines. Some key pros are that it provides accurate answers using internal data sources and saves time over traditional research. However, it may provide too much information and take away from learning research skills. Overall, it has benefits for teaching and learning by providing visual aids, showing mathematical steps, and making information easier for students to find.
