Hello Parents and Students!

I frankly thank you for spending the time surfing or just happened to stumble onto this site. Whether you are searching for extra assistance in long-term, short-term, or just to brush-up the concepts for an upcoming assessment or standardized test then you have visited the right place.

My name is Andy, A.K.A the “Math Magician” preferred by most of my high school students because they are always amazed and love the way I translate complex and difficult problems into very simple ones. Both teaching and tutoring have been part of my life for the past twenty years. Both teaching and tutoring have been part of my life for the past twenty years.

Over the course of my teaching and tutoring career, I have carefully observed and formulated three important components that are valuable assets and essential to help students change the way they think about math. I called these components the Right Styles, Right Techniques, and Right Mathology.

My desires are not only to help students get through with their daily homework, to ace the test and forget everything afterward. However, to help them develop their critical thinking process by providing concise questions and feedback, challenge them with difficult problems to stimulate their brain to enhance long-term memory, and criticize their mistakes for them to acknowledge and improve upon.

At the end of the day, I believe that a good mentor is comparable to a good doctor with magic hands, sound background, and solid experience in their prospective fields of practice that can diagnose and provide the right treatment on the first or second visits to save the patients' time and money.

Thirty years from now, it does not matter how much money I have in the bank or what kind of car I drive, what matters most is how many lives I have effected.

Cheers,
Andy

Statistics

Statistics

In general, statistics is fun and interesting, especially an introductory course to statistics because it focuses more on how to gather, organize, and analyze data. The used of algebra is minimal so you don’t need to be a math whiz to take an introductory course in statistics. I have tutored high school and college students, especially adult students, who returned to school to further advance their career and opportunity—majority of them struggled and found it difficult since they haven’t done math for years. As your tutor, I will help you understand the underlying theory with step-by-step instruction so that you will always enjoy much greater success if you understand what you are doing, instead of blindly applying mechanical steps in order to obtain an answer that may or may not make sense.

Homeschool

Algebra 1,

Algebra 1

Algebra 1 is great fun – you get to solve puzzles! You play some computer games by running, jumping or finding secret doors. Well, with Algebra you play with letters, numbers and symbols. And once you learn some of the “tricks”, it becomes a fun challenge to work out how to use your skills in solving each “puzzle”.
Algebra 2,

Algebra 2

Algebra 2 is really fun, interesting, and challenging because it required the knowledge and skills of algebra 1 and geometry. In fact, I’ve taught both Honors and regular Algebra 2 for a decade and I’d enjoyed every moment of it. I have many short cuts and tricks to help students to memorize formula, know how to graph different types of functions, and solve certain equations as well as solve word problems effectively.
Calculus,

Calculus

I tutor AP Calculus AB/BC, Business Calculus, and Calculus 1, 2, and 3 with excellence successes rate. Students who took the AP Calculus exam, 80% of them passed with a score of 5 and 20% with a score of 4 or 3. I tutor college students at CSUF, CSULB, UCI, Fullerton College, San Ana College, Irvine Valley College, Orange Coast College, Golden West College…just to name a few. In general, I love to figure out math problems, especially calculus problems. I guess because there is always a right answer and there can be many ways of going about getting that answer. Unlike English, an essay can never be perfect, it can never be completed—there is always something more that can be done. I told my calculus students that math skills are like muscles in your body, if you don’t work out you won’t go anywhere. Therefore, you just practice, practice, and practice in order to do well in calculus.
Geometry,

Geometry

Geometry was totally a different playing field for me when I first took it in high school because I used to have hard time in grasping the concepts of proofs and know how applied the definitions and theorems. Geometry is more of a visual subject—requires more abstract thinking in analyzing shapes and figures. But now, after teaching Geometry classes for ten years, I’d really like the subject and I personally think it is easier than Algebra since it doesn’t involve with solving complex equations. Despite the fact that Geometry is not as hard as algebra, I still suggest that students must know the definitions, axioms or postulates, theorems, and formula to in order to do well.
Prealgebra,

Prealgebra

Many students find algebra to be a very interesting subject. However, some students find algebra to be very difficult. Often the reason for this is that they have not yet mastered the concepts of pre-algebra. This is why it’s so important to for students to learn pre-algebra thoroughly before moving on to higher levels of math. If students start doing various kinds of math problems early in their studies, they are less likely to encounter problems further down the road. Exponents, arithmetic equations and basic graphing are other primary topics in pre-algebra. These are the pre-algebraic concepts with the widest applications in everyday life. Their applications are almost countless. These concepts of pre- algebra are used in almost every field in business and the sciences. From small-scale business to huge engineering projects, algebra plays a central role in solving problems. If the student wants to have a career in business or the sciences, it’s important that he/she learn pre-algebra as a stepping stone to higher mathematics.
Precalculus,

Precalculus

Precalculus prepares students for calculus the same ways as pre-algebra prepares students for Algebra I. While pre-algebra teaches students many different fundamental algebra topics, precalculus does not involve calculus, but explores topic that will be applied in calculus. Precalculus was a fun challenging course that I went through in last year of high school. There are three main components of precalculus that are so vital that I suggest students must know: 1. Know how to represent functions. There are many different ways you can describe a functions, the most popular are algebraic and graphical. 2. Know the basic function library. Knowing the basic properties of common will save you a lot of time in your calculus studies. Basic functions include trigonometry functions, exponential function, polynomials, and many more. Each set of functions has unique properties that make them useful in different ways. 3. Know how to transform functions. Basically this is taking one function and turning it into another through a set of manipulations—shifts, stretches, and compressions.

Differential Equations,

Differential Equations

Differential Equations is one of the most useful and interesting mathematics classes that I've taken as an undergraduate because begins with some definitions and terminology and mathematical models used in a differential equations course. First-order and higher-order differential equations, along with the methods of solutions and their applications are introduced. Modeling with higher-order, Laplace transform, and systems of linear first-order differential equations are covered. At the end, students learn series solutions of linear equations. Numerical methods are covered throughout the course. I have been tutoring students from CSUF and Santa Ana College for two semesters and I enjoyed every moment of it.
Discrete Math,

Discrete Math

I am comfortably tutor students an introductory course in discrete mathematics. The goal of this course is to introduce students to ideas and techniques from discrete mathematics that are widely used in science and engineering. I can teach the students techniques in how to think logically and mathematically and apply these techniques in solving problems. To achieve this goal, students will learn logic and proof, sets, functions, as well as algorithms and mathematical reasoning. Key topics involving relations, graphs, trees, and formal languages and computability are covered in this course.

Linear Algebra,

Linear Algebra

Linear Algebra is one of the most useful and interesting mathematics classes that I've taken as an undergraduate because it's involved with vector spaces and linear mappings between such spaces. It includes the study of lines, planes, and subspaces, but is also concerned with properties common to all vector space. In addition, this course is very helpful in preparing for Differential Equation course. I have been tutoring students from CSUF and Santa Ana College for the past two years and I enjoyed every moment of it.
Logic,

Logic

This class has trained me to be comfortable and competent in using logical tools to analyze and understand arguments and to form my own. In the process of familiarizing myself with these tools, I was able come to a deeper understanding of the process of argumentation itself – recognizing in greater detail the underlying structure of the arguments that bombard us every day and being able to respect and evaluate the various elements that can make those arguments strong or weak.

Trigonometry,

Trigonometry

Trigonometry is one of my favorite math concepts due to the fact it has many real-life applications. Trigonometry is really isn’t hard. If it seems hard, then that’s because you were taught in a manner that doesn’t work for you. Different people learn different ways, but teachers sometimes only teach one way, whereas the way you are taught needs to be the way you learn. There are only three important definitions in trigonometry. Everything else is based on those three. If you can understand these three definitions, you should have no trouble understanding any other part of trig. The three most important definitions are: Sine of the angle = opposite/hypotenuse Cosine of the angle = adjacent/hypotenuse Tangent of the angle = opposite/hypotenuse Yes, trigonometry finds itself enmeshed within our world. The three trigonometric functions do more than tell us the ratio of sides of a right triangle; they help tell us about life itself. Keep this in mind next time you run into the sine, cosine, or tangent.

Featured review

The BEST tutor ever!! Brilliant, Patient, and Knows how to teach!

So, I am one of those people who used to breeze through algebra classes by memorizing formulas and doing just enough to pass with an A, then forget everything right after that final test...well, such practice took its toll on me when I took Business Calculus this semester. My weakness from slacking off in algebra started to pull me down along with these new crazy calculus problems my professor would throw at me. After barely making it through my midterms, I decided I couldn't go on anymore without getting some help. At my first session with Andy I immediately knew that he was going to be the one to save me from this pit I was in. We started off slowly with going over some problems I'd missed on my midterms, then after that he'd help me with my homework and extra credit problems. I struggled to learn from basic algebra concepts to abstract calculus problems, but Andy was very patient with me and gave me time to absorb the information calmly. He is very knowledgeable and really knows how to teach. He actually has a real teaching experience--he used to be a high school Math teacher. Whenever we were going through a problem and I'd have a chain of questions, it was amazing to see him explain as if he anticipated all these questions that would pop up in my head. He's talented in explaining abstract math problems in a simple and easy to understand words and is brilliant in making connection between the subjects being learned and the ones that we learnt before. I had so much fun during our sessions because there was so many "Ah-ha!" and light bulb moments. Particularly when I grasped the concept of the triple integrals after a long difficulty trying to understand them, it was exhilarating! I never had so much fun learning math as much as this! I could tell that Andy really loves the subject especially when we're solving tricky extra credit problems (I'm telling you those were real, I mean real brain stretchers) his eyes would light up and boy, the way he solved through those problems as he explained them to me, I'm like speechless! He is extremely smart! Plus, there is no better person to learn from than the person who loves what they're teaching. Some people may laugh at me for fussing over Business Calculus because it's "watered down", but hey it's still all calculus 1,2,3 combined and the class I took was so difficult that half the class dropped out. If it wasn't for Andy I would've been one of those poor souls. Instead here I am, happy with my solid A, writing up this long review for him because I don't know how else to thank him! So to everyone struggling with any levels of Math out there! Take my word, Andy is no doubt a "Math magician" so give yourself a chance to see his magic at work!

Help with AP Calculus Test

Andy quickly determined what was needed to help on an upcoming AP Calculus test. He was professional, had good communication and offered good, alternative ways to solve the same problem.

Stephen, 1 lesson with Andy

Patient, helpful

Andy helped me figure out trig-sub and was very patient with me when I took a while to understand what he was doing. He also helped me out with partial fraction decomposition and took time to explain how to do it, and was able to explain several times when I missed something.

Excellent Geometry Tutor!

I found Andy on this site and selected him based on his glowing reviews and his bio. I really liked where he said he teaches Geometry so that students are not only prepared for tests but so that they actually understand the concepts. My Sophmore student learned so much from just one session and ended up doing really well on her Geometry test! We highly recommend Andy for anyone who is struggling with math!
