About David

My name is David U., but many just know me as Dave the Math Tutor. I've been a professional math tutor for over 30 years, and I can help you make sense of anything mathematical, from elementary arithmetic to pre-algebra, algebra, geometry, trigonometry, pre-calculus, calculus, differential equations, linear algebra, statistics, probability, number theory, and more, including test prep for tests like the ACT, SAT, CBEST, CSET, GMAT, and GRE. With me you can learn to master the basics, then bump your grade up a notch by learning the shortcuts to take, the pitfalls to avoid, and the special tricks that can make your work quicker, easier, and less prone to error.

I have a B.A. in Math and a wealth of experience working with students of all ages and levels. My students often tell me they appreciate my broad knowledge, my enthusiasm and love of math, my clear and straightforward explanations of mathematical concepts, and my patience and good humor. I'm available days, evenings, and weekends, and I'd love to help you master math.

My rates are reasonable but not low; you can easily find cheaper math tutors. Finding a better tutor, though, would not be so easy! So when quality is more of an issue than price, get in touch with me and find out just how helpful a top-notch tutor can be. I look forward to working with you.

Thanks, Rachel! I'm glad my tutoring helped, but the lion's share of the credit goes to you. You worked super hard this summer, and together we accomplished a miracle! All the best to you in your future studies.

David replied on 5/13/2014

Thanks, Teruko! Your daughter is a very sharp student - the kind who's not satisfied with memorizing formulas, but works to understand them on a gut level. Working with her is a pleasure!

"Very knowledgeable, professional tutor."

Approved subjects

In most cases, tutors gain approval in a subject by passing a proficiency exam. For some subject areas, like music and art, tutors submit written requests to demonstrate their proficiency to potential students. If a tutor is interested but not yet approved in a subject, the subject will appear in non-bold font. Tutors need to be approved in a subject prior to beginning lessons.


The CBEST is an exam that's not very difficult. The math it requires is mostly just standard algebra and geometry. Any decent math tutor is sufficiently knowledgeable to tutor for this test.

In my case, I have 30 years of experience in tutoring not only algebra and geometry, but also trigonometry, calculus, differential equations, statistics, number theory, and more. I have also tutored specifically for the CBEST on a number of occasions. I am highly qualified to tutor students needing help in preparing for the CBEST exam.

Differential Equations

I look at differential equations as a game, and that's how I teach it: This is the objective, these are the rules, here are some helpful tricks you can use. This approach certainly worked well for me in my own studies; when I took a course in differential equations on my way to earning the degree I hold (a B.A. in Math), I understood the material so well that I scored 100% on every exam, including the final.

Likewise this way of looking at differential equations seems to have worked well for the dozens of differential equations students I have tutored over the past 25 years. A good many of them have enjoyed excellent outcomes, mastering the material well and achieving high grades in their courses.

It worked for them, and it can work for you too. Treating differential equations as a game makes it fun and easy!

Discrete Math

Discrete math includes topics such as summation with sigma notation, mathematical induction (both weak and strong), combinatorics, and graph theory. These are all subjects I have studied extensively in a variety of settings: in courses I took on the way to receiving my bachelor's degree in math, in my work over the past 30+ years tutoring students who were dealing with these topics in their courses, and privately just for my own pleasure. I have already enjoyed considerable success tutoring these topics outside the WyzAnt system, and I am eminently qualified to pursue these topics with WyzAnt students as well.

Linear Algebra

A linear algebra course typically begins by considering matrices as a tool for solving systems of linear equations, which is a fairly mechanical process, and then progresses to the very abstract realm of vector spaces, in which a "vector" need not involve numbers at all, and "addition" and "multiplication" may be defined as something completely different from the familiar arithmetic operations we've used all our lives. Working with this latter type of problem requires thinking outside the box. That's something I'm good at, which is why I was able to sail through the three Linear Algebra courses I took on the way to obtaining my B.A. in Math, earning A's in all three of them. I've had a good deal of success as well in helping my own Linear Algebra students master these skills, during the 25 years or so that I've included that subject in my work as a professional math tutor.

Both aspects of Linear Algebra, the more mechanical operations and the more abstract problems, are important. Both by my academic training and through my accumulated experience as a tutor, I am well qualified to help students achieve mastery in this fascinating yet sometimes challenging subject.


I have been a professional math tutor for more than 30 years, and in that time I have tutored a number of students in the area of Symbolic Logic; currently I am in the process of writing an Introduction to Symbolic Logic. Logic has always come very naturally to me; I began studying it when I was 12 years old (which was a long time ago!). In the course of pursuing my bachelor's degree in Mathematics, I took (and earned A's in) two separate courses in Logic, one offered by the Math department and the other by the Philosophy department.

Some of the topics covered in those courses were: Logical statements and truth values; negation; conjunction, disjunction, and implication; truth tables; De Morgan's Laws; syllogisms; conditional statements and the inverse, converse, and contrapositive; proof by contradiction (a/k/a indirect proof, reductio ad absurdum); logical equivalence and the biconditional; proof via truth tables; tautology; contradiction; and paradox (including the Liar Paradox and Russell's Paradox). I am well qualified to teach all these topics, and more.
