About Charles


Bio

Hi,

My name is Charles. I’m a retired college professor. I am an economist and applied mathematician. I taught economics, finance, and applied math at the State University of New York (SUNY).

I’m also a part-time member of the U.S. Coast Guard.

I tutor all levels of math including, calculus, linear algebra, elementary school, junior high school, and high school math. I also tutor students in economics, as well as probability & statistics. Additionally, I’ve taught students taking the AP...

Hi,

My name is Charles. I’m a retired college professor. I am an economist and applied mathematician. I taught economics, finance, and applied math at the State University of New York (SUNY).

I’m also a part-time member of the U.S. Coast Guard.

I tutor all levels of math including, calculus, linear algebra, elementary school, junior high school, and high school math. I also tutor students in economics, as well as probability & statistics. Additionally, I’ve taught students taking the AP courses in calculus, statistics, and economics. I also tutor for the SAT, GRE, and GMAT. When I took the GRE exam I got perfect scores. The GRE is like the SAT on steroids. It’s used when applying to graduate school. When I took the SAT many years ago, I got nearly perfect scores.

My research and publishing has all been in the area of mathematical economics and finance. My work has also incorporated a great deal of material in the areas of philosophy, history, literature, physics, etc. Over the years I have developed a deep understanding of these areas.

Consequently, in my teaching of math and economics I have incorporated some material on the philosophy of math, philosophy of economics, philosophy of science, as well as the history of these disciplines. I have seen that this helps the students. They find out where the math comes from and how we got to this point in our understanding of the material. It makes learning math and economics less dry. It enriches the learning experience. And it makes tutoring sessions more interesting and more fun. But ultimately, the goal is to improve the student’s understanding of the material and to raise the student’s grade.

I have published several scholarly papers and two books. My understanding of the subject material comes from doing research and publishing, teaching at the university level, and handling some consulting assignments over the years.

I live in Huntington, New York. I used to live in St. James near Stony Brook University. I moved a few years ago to be closer to my frie

Elementary Math

Elementary math is important since it provides the fundamentals for all the math to come in higher grades. Students learn more when they also learn the history of the math and how it’s applied. Which are both areas I try to incorporate into my teaching.

Homeschool

Calculus,

Calculus

Calculus is one of those subjects that is really interesting. When I first took calculus it opened the world up to areas I had never thought about. I learned more about the world from calculus than any other subject I ever took in school.
Geometry,

Geometry

I’ve tutored students in geometry for about 20 years. One of the biggest concerns of students taking geometry is learning the proofs. Since this is their introduction to proof writing. Fortunately, I am able to make proof writing fun and my students always master this part of geometry. Moreover, geometry should be the most fun for any student. Look around your room. Look at all the shapes and dimensions. Then think about area and volume. Geometry is a part of every life every day.

Dedicated and Accommodating

Charles is flexible and willing to work with us and our busy schedule. He knows how to ask the right questions and push my child to think about his economics. Charles takes pride in having his students make 5's on the AP tests and it is evident in how he works with my son!

Stacey, 3 lessons with Charles

Knowledgeable, Professional and really cares if you learn.

I have used Charles for over a month, in preparation for the GRE General Exam. He is prepared, on-time, never cancels and know his Math quite well. Math is my weakest subject, but no matter how challenging an equation is, he always works it through with me so I can master it. He has been instrumental towards restoring my confidence in my highly limited knowledge of Math. And when I have a question over the Weekend in between sessions, he answered them promptly and accurately. He doesn't just tutor for the money, but actually cares that you learn. With Charles, you are absolutely 100% getting what you pay for.

Great Tutor

Mr Kaplan made everything so much easier. He explains everything in a simple, easy to understand way. He is definitely one of the best tutors I've had.

Janina, 4 lessons with Charles

Great teacher in Managerial Economics!

Professor Charles was very helpful with my managerial economics class! Without him I would not have been able to get a 93 on my assignment so I am very grateful. Professor Charles was willing to help super last minute when I was in a time crunch--I see myself booking many lessons with him in the future.

Exceptional AP Micro Economics Tutor

Charles K. basically taught my son AP Micro Economics. We found Charles in mid-December when my son had a solid D- in AP Mirco. At our school midterms occur in mid-January. Over the course of 4 weeks, Charles patiently taught my son Micro and my son went from thoroughly lost to a B+ on the midterm exam. The second semester he also got a B+ and he got a 4 on the AP test. Charles also has a great personal touch. Charles and my son got along great, Charles knows how to make personal connections. I HIGHLY recommend anyone in need of Micro Economics assistance to hire Charles asap.

Patient and knwlogeable tutor

Charles is teaching my daughter Math. since she started with Mr. Kaplan her grades have gone up from an average B to A+. along with her grades her math skills have improved and became very confident.

Nazia, 42 lessons with Charles

Knowledgeable and patient tutor

He explained the concepts really good and built up from them. He also gave more general interesting information about the subjects that helped bring it together.

Iris, 6 lessons with Charles

Extremely knowledgeable, great tutor!

Charles and I worked on Econ and he makes the material much easier to grasp. Wonderful to work with and I would highly recommend. Great tutor and a really nice guy!

Reid, 24 lessons with Charles

Great tutor and very knowledgeable

Charles has a great love of Math and it shows in his tutoring. He is really great with my daughter. She really enjoys working with him and even says he is funny. He keeps the work fresh and fun. He is tremendously knowledgeable and has a really good teaching method. She has only had 2 lessons so far, but she is learning a lot.

Laura, 9 lessons with Charles

Very knowledgable, patient, kind and an exceptional teacher

He taught me a lot about economics that I could never learned or understood on my own; he made me realize that these are techniques that I use every day, but because they are thought of and used differently I make them harder than what they really are. I can not thank him enough.
