Dr. Ivan Retamoso holds a Ph.D. in Mathematics from The Graduate Center of New York and a Masters Degree in Mathematics from The City College of New York.

Before joining the Mathematics Department at BMCC, Dr. Retamoso taught Mathematics and Statistics at several CUNY Colleges, mainly at Baruch College, Brooklyn College, The City College of New York, and Kingsborough Community College. His main research interests are in Computational Mathematics, Polynomial Root finding Algorithms, and Teaching Mathematics using OER/ZTC with Technology.

Dr. Retamoso speaks English and Spanish fluently and is in the process of learning Russian. He loves to learn about other cultures and enjoys meditation in his spare time.

## Courses Taught

- This course covers basic algebraic and trigonometric skills, algebraic equations, and functions. Topics include: mathematical induction, complex numbers, and the binomial theorem.

Prerequisite: MAT 56 or MAT 56.5

Course Syllabus - This course is a combination of arithmetic and elementary algebra. It includes the arithmetic of integers, fractions, decimals, and percent. In addition, such topics as signed numbers, algebraic representation, operations with polynomials, factoring, the solution of simultaneous linear equations of two variables, and graphing are covered.

Students who passed MAT 12, MAT 14, MAT 41, MAT 51, MAT 56, MAT 160, MAT 161, MAT 56.5, MAT 150.5 cannot take MAT 161.5.

Course Syllabus - This course is the first algebra course offered at the College. It includes such topics as algebraic representation, signed numbers, operations with polynomials, factoring, the solution of linear equations, the coordinate system, the solution of simultaneous linear equations of two variables, and graphing. This course is designed to prepare students for the CUNY Freshman Skills Assessment Test required for transfer to the upper division of CUNY, as well as for more advanced math courses. If a student passes MAT 12, the student should not register for MAT 51, since MAT 12 combines MAT 8 and MAT 51.

Students who passed MAT 12, MAT 14, MAT 41, MAT 51, MAT 56, MAT 160, MAT 161, MAT 56.5, MAT 150.5 cannot take MAT 161.5.

Course Syllabus - This is an integrated course in analytic geometry and calculus, applied to functions of a single variable. It covers a study of rectangular coordinates in the plane, equations of conic sections, functions, limits, continuity, related rates, differentiation of algebraic and transcendental functions, Rolle's Theorem, the Mean Value Theorem, maxima and minima, and integration.
Prerequisite: MAT 206 or MAT 206.5

## Research and Projects

I have created websites for all courses that I teach.

https://openlab.bmcc.cuny.edu/members/iretamoso/

Since Fall 2019, I have been using for all courses that I teach:

Zero cost OER Textbook from openstax.org

Zero cost WEBWORK Homework system.

Zero cost Homework system from: http://helpyourmath.com/immersion/homework

It is my intention to help students learn Mathematics regardless of their financial status.

Currently,

I am an ACCCESS Fellow member of the sixteenth cohort of AMATYC Project ACCCESS.

I am a Faculty Fellow for the Opening Gateways Faculty Seminar.
