The Web site provides online tutorial assistance for students struggling with their math homework. When students are stuck on a particular problem, they can go to the site and select their textbook and problem number to begin a tutorial on their specific problem. The site gives hints, asks Socratic questions, uses graphs and figures, and shows a step-by-step description of the solution through to the final answer. Students can use the site for help on tough problems or to check their work at home, while teachers can use the site in class to demonstrate different problem solutions.
