Do you want to receive tutoring from a professional mathematician?

I am not only a research mathematician in my field, but also an experienced

PROBLEM SOLVER that covers all subjects in high school and most of

undergraduate mathematics:

Calculus, Linear Algebra, Probability and Statistics, Discrete Mathematics,

Operations Research, Vector Calculus, Differential Equations,

Differential Geometry, Abstract Algebra, Topology, Complex Analysis, etc.

Fax any math problems to (718) 779- 4846. Or e-mail me at takaoueda@juno.com.

I will immediately send you step-by-step solutions, unless the problems are extremely hard.

Levels: High school to College.

Fees: From $1 per simple question (simple questions include SAT I, II, GRE, etc.).

Payment methods: Checks, money orders, PayPal.

I use the following software upon request or if necessary.

Programming: QBasic, C++.

Math system: Maple.

Graphing: GNUplot.

Drawing: Xfig.

Writing: WordPerfect, MS Word, LaTex.
