My name is Dorian Ehrlich, I am a mathematician, statistician, programmer and most importantly, a dedicated math teacher. My two professional passions are using traditional applied mathematical and statistical methods to analyze data, and teaching math.

As a math tutor, I have worked with young men, young women, students from many religious backgrounds, nonbinary students and students “on the spectrum.” I worked with jocks, gamers, underachievers, overachievers and those who were meant to work with their hands instead but had some math talent nonetheless. I worked with students who were clearly bright that others had given up on, and I have worked with the crown jewels. I have also worked with students who happened not enjoy math or performed below their peers in math. I have even worked with students whose math ability surpasses my own. I have had success and formed bonds with all of these students and it was and always will be natural for me to do so. To put it in a sentence, the way to get it done is first to know the math yourself on the deepest of levels, and then to be willing put what you know in their words and their world, and to be their *unconditional* friend and ally.

Approved Subjects

Algebra 1

Algebra 1

I have extensive experience working with students in Algebra 1, particularly in the in-person, school setting. I have experience working with a particularly wide range of math abilities in this subject and have delivered passing final exam grades to many students who thought they would fail going into our work together.
Calculus

Calculus

The reason I feel I can be of great help in calculus is that I know it’s really the details of the course that come, most especially from not allowing yourself to understand or believe the concept of a limit, that holds bright students who otherwise get the thrust of the course back from getting the grades they know they are well capable of. I know this because I am someone who had to take what was known in 2010 as “Calc I”, as a freshman in college, and needed four 2-hour tutoring sessions particularly on limits and solving problems during my fall break at home to turn a 60 on midterm 1 into an 88 and curved A, on midterm 2 when I came back refreshed to college. From the calculus course I took, and the many, many hours of learning and practice calculus problems I have done myself on my own time since graduating college, I can speak to the intuition behind what may be occurring at too quick a pace in your math course. I will also add that my personal hero is Sal Khan of Khan Academy, and I learned calculus from his oldest and rawest videos, first and foremost. He originally made his videos to tutor his niece, and so my style is in fact most deeply rooted in a need to educate those who are seeking deep wisdom to unlock problems and a desired grade.
Geometry

Geometry

I tutored Geometry and led large review sessions for Geometry finals in the in-person, school setting for two years. My experience with this subject is that it is the scariest of all high school math subjects, including Calculus, and it has been a devil to some of the best math students I have worked with. Many students even go on to do well in Algebra II after struggling hard in Geometry. The key with geometry is to ditch memorization completely and put aside what you know from Algebra I with this course when working on problems, and give yourself the freedom to grasp the new mechanics of writing proofs at a slow and steady pace.
Linear Algebra

Linear Algebra

My experience teaching Linear Algebra comes from my past experience taking the subject myself as a college sophomore, tutoring in the subject on this platform, revisiting the material many occasions on my own time and most especially, from the two semesters where I worked as a grader for my graduate regression class. Whether your Linear Algebra class is more theoretical or more based on problems, we will get to the bottom of the new kind of thinking this class forces you into together.
Statistics

Statistics

I am a current Master's student in statistics and have both tutored and graded statistics at the graduate level. While it is tempting to approach a statistics course as an unfair memorization exercise, in my experience, statistics is mastered by understanding the math and the intuition behind what you're doing. By making sense of why the formulas appear as they are, I find that students are able to "know" the formulas without cramming for tests.
Trigonometry

Trigonometry

My goal in trigonometry is for my students to know the unit circle in and out, and use that singular concept as the basis for understanding any question about sines, cosines and tangents.
