About Us

MobileCaltronics is a small upstart company licensed in Fl as a Limited Liability Corporation, using the ficticuous name MobileCaltronics. I am the owner and President of MobileCaltronics, Singh Kelly. My background is in education, and I still teach full-time at Baton Rouge Community College.

Just prior to my graduate work and continuing through the first year of my studies I was the manager of a Math/Stats lab, 1989-1993 in pensacola, Fl. Before I managed the Lab I taught Physics, Algebra and Geometry at a local high school. I received my Master's degree in Pure and Applied Mathematics in 1995, and began teaching with graphing calculators during my graduate assistantship as part of my TA duties. I immediately recognized technology as a wonderful tool that helped students understand the concepts of Mathematics and Statistics.

For the first few years after receiving my M.S. degree, I taught almost exclusively College-Preparatory courses at a Community College in Central Florida where I was one of ten instructors nationwide piloting several different Computer Learning Systems for Basic Mathematics, Prep-Algebra and Intermediate Algebra. This was a couple years before Windows 3 & the Internet so everything dealing with the computer was MS_DOS and "floppy disk"; however, even with those crude first programs I quickly realized how the computer learning programs could reach some students that were previously not reachable. I have also come to realize over these past years how the computer allows interaction with wholly new sets of students that were previously unaccessable due to either time constraints, physical distance, monetary issues, or job requirements.

In 1995 I wrote my first manual for the graphing calculator simply because at that time no one else had! I still own the original copyright to the first graphing calculator manual for Statistics, although all future writings I sold to Prentice-Hall, now Pearson Publishing. My first nationally published manual is now in its 5th edition and has sold over 50,000 copies. I followed that first manual with 8 additional manuals ranging from Elementary Statistics to Engineering Statistics to Bio-Statistics to a general technology manual that accompanies many different publications. I have taught several different styles of Distance Education courses, from TV remote broadcast Calculus to Internet-based College Algebra. I am recognized in the 1998-1999; 1999-2000 Who’s Who Among American Teachers.

In the Spring semester, 2008, I noticed so many students had smart phones that I began to wonder when TI was going to come out with a mobile App that would replace the hand-held calculator. By fall of 2008 I realized they had no plans to do that - so I did. I started asking friends and relatives to help me learn how to program these Apps for myself. After almost 2 years of work, and a lot of help from several people, I am able to offer you these APPs that completely replace the need for you to carry a separate hand-held graphing calculator to class.

I have always believed that technology should be welcomed as a tool for education, without fear of it being just a crutch for students.
