About Mark S.

Subjects

Algebra 2, Discrete Mathematics, Pre-Calculus, Statistics

Education

Bachelors in Mathematics, General from California State University-East Bay

Career Experience

Most of my professional career was spent as a software engineer developing software which runs on the various flavors of the Microsoft Windows operating system, as they developed over the years. It was interesting and well-paying work. I am now semi-retired but wish to give back to the world what was given to me by the many good and hard-working faculty members at academic institutions I have attended.

I Love Tutoring Because

it is satisfying to me to help students who may not consider math or science their favorite subjects, but get to the point, with my help, of having that aha! moment when they grasp the concepts governing the problems they are working on.

Other Interests

Computer programming, Cooking, Foreign language learning, Gardening, Hiking, Listening to Music, Reading, Weightlifting

Mr. Mark S was incredibly helpful during our session! He took the time to explain adding and subtracting rational expressions in a way that really made sense. On top of that, he went above and beyond by helping me with solving rational equations, even when I was struggling at first. His patience and clear explanations made a huge difference, and I feel much more confident now. I really appreciate his dedication and the extra effort he put in to make sure I understood everything. Thank you so much, Mr. Mark!
