Yakov Rolbin ; Math, 6 -7, 7-8 For several years I worked as a high school mathematical teacher. At the same time I did a research projects in the field of mathematical methods in economics. That allowed me to partake in a doctorate degree. I earned Ph.D. in Math Methods in Economics at Moscow Finance Academy, Russia. Then I worked as a Professor in Kazan Finance Institute and Institute of Management of Airspace Industry of Russia. In the United States I worked at Hackensack High School as a Math tutor. There I had to work with a special contingent of students who need non-standard methods, ideas, and concepts to interest students in the subject. I also kept lessons in different afterschool programs in New Jersey. As the greatest award I store letters of thanks from my former students who went up to prestigious colleges of America. My main areas of Math courses: Algebra I Geometry Algebra II Pre-calculus Calculus Statistics Probability
