My name is Larry Feldman, and I specialize in making complex material understandable to a mass audience. I have a MSEE and over twenty years of applied mathematics and teaching experience. I firmly believe that every person has the ability to comprehend mathematics as long as the material is presented in the right way. Most complicated problems can be broken down into simpler components.  I strive to help students figure out how.

If you're looking for applications that simply list formulas, there are plenty to choose from on the iTunes App store written by other authors. My applications provide formulas too, but they also solve complex problems and explain the concepts behind the formulas.

Students will learn a great deal from my applications, and they will gain the ability to check their homework answers quickly. Students, teachers and other professionals will appreciate the ability to obtain answers to their questions in the blink of an eye. 

My apps do not collect, request, store, or share any personal information or location data.
