Great!!!
It offers great equations if seem to forget it, i do wish that they had economic formulas.Need heaven!
If only this app were available when I needed it most: in high school and college. Better than any other calculator available and helps you learn the formulas, too! Highly highly recommend.Simple and user friendly
A great tool for any one in high school or college . A user friendly interface and a great approach of teaching the subject with the wiki link website is a nice touch. Hoping for future updates for more specific subjects from the developer - civil , mechanical engineering etc.
