This is an excellent tool to learn how to solve math problems. Students type the story problem. And the software is giving the answer in step-by-step solution. All the steps and explanations help students to understand how to look at a problem, see the key words, and reach to solutions. I think this can help parents to help their children in math as well.
It is a great mathematical software for children from third grade through college. Students get better understanding of some abstract things about math. There is a section you can try it free and get a feeling of it. Students can start making sense by making connection between numeric and graphic representations.
