Algebra 1

Algebra 1 is the first math class that introduces equations with variables and how to determine solutions for equations with first one and later with two variables. In Algebra 1 we also study graphical methods in order to visualize functions as straight lines or parabolas. Further we learn about factorization and the solutions of quadratic equations. Seeing many advanced students who struggle with algebra 1 concepts makes me feel good about my algebra 1 students because I help them to learn it...

Algebra 2

Algebra 2 introduces independent and dependent variables and how their solution can be determined by for linear relationships for two or three variables. Algebra 2 also gives an overview of more complex mathematical functions like basic trigonometric functions, power functions, logarithms, and exponential functions. I tutor Algebra 2 almost daily and based on my tutoring experience in more advanced topics I know very well which areas of Algebra 2 are important in further math classes.

Calculus

Calculus is my most tutored subject. I tutor high school, college, and university students on a daily basis in AP Calculus classes and in single and multivariable calculus courses at colleges and universities. I also teach calculus to individuals outside of any class. I supervised small groups with aspiring math teachers learning calculus and I taught for several years my own university courses that built heavily on calculus. More than one third of my tutored hours covers calculus.

Precalculus

Precalculus is the gate to calculus and provides a comprehensive view of the behavior of polynomials, rational functions, and trigonometric functions. I tutor high school, college, and university students on an almost daily basis in Precalculus. I emphasize the understanding because it will not only help in getting better grades but also serves structural learning.

Statistics

I worked for many years professionally with statistics and next to precalculus and calculus it is my most tutored topic. Statistics doesn't require advanced math classes but it requires a good understanding how to translate word problems into a mathematical form and vice versa. Most classes cover descriptive and inferential statistics using extensively the normal distribution, which also plays with the Student t-distribution a key role in hypothesis testing. I tutor statistics multiple times a...

GRE

I help at all levels of math including the test preparation for the quantitative part of the GRE. I had several GRE students and they all exceeded their initial expectations in the math portion.

"Excellent tutor improved my GRE score!"

- Megan G. Oakland, CA

Andreas was a huge help to me in preparing for my GRE. We met several times and his combination of patience and humor helped to keep me on track despite my admittedly deep-seated math phobia. I hadn't taken a math class...

Discrete Math

I have a B.Sc. in Economics/Operations Research and I studied optimization, graph theory and applied Operations Research methodology to research and modeling.

####
Differential Equations

I worked more than 10 years in research using different forms of differential equations covering stiff ODEs and multidimensional equations in Computational Fluid Dynamics applications. I tutor on a regular basis university students in calculus and differential equations.

####
C++

I worked for several years as a Software Engineer at Lawrence Berkeley National Laboratory (LBNL) using C/C++ for projects using high volume databases for distributed storage systems.

####
Computer Science

I have been working in computer science related fields in research (Academia & labs) and industry. My PhD thesis is in numerical models for high performance computers. I also worked for several years for a company modeling hazards based on data driven computational models.

####
Fortran

I used Fortran for many years in high performance computing for climate research models and non linear finite element systems.

####
Linear Algebra

Linear Algebra investigates the linear relationship between multiple variables. On one side it is for many students a first encounter with mathematical abstraction and on the other side it is a topic that occurs in many scientific applications like in numerical or economical models. At different universities I taught my own courses that built on linear algebra. I also taught groups with aspiring teachers in linear algebra.

"Great Tutor"

Logic

I learned formal logic as part of my mathematical education and I additionally studied the use of logic as part of set theory and computer science. Logic supports the understanding of basics and limitations of theories like math, sciences, and philosophy.
