### This note is especially for beginners.

Maybe you need to pick up "some" basic "mathematics" rather *quickly*.

So really..., my emphasis is on "rather *quickly*".

So, I am not sure of it, but I hope that this note can be of use.

Ofcourse, I hope you like my "style" and try the note anyway.

Preceding notes, which are all ready:

Note 1: Basic Arithmetic.

Note 2: Linear Equations.

Note 3: Quadratic Equations and polynomials.

Note 4: The sine/cosine functions.

Note 5: How to differentiate and obtain the derivative function .

Note 6: Analyzing functions.

Note 7: The e^{x} and ln(x) functions.

Note 8: Primitive functions and Integrals.

Note 9: Complex numbers.

Note 10: Differential equations Part 1.

Note 11: Functions with two or more variables.

Note 12: Vector Calculus / Linear Algebra Part 1.

Note 13: Fourier- and Taylor series.

Note 14: Surface and Volume integrals.

Note 15: Statistics and Probability calculus.

Note 16: Vector Calculus / Linear Algebra Part 2.

Note 17: The Grad and Div operators.

**This note: Note 18: More information on R**^{n} -> R^{m} functions and mappings

Each note in this series, is build "on top" of the preceding ones.

Please be sure that you are on a "level" at least equivalent to the contents up to, and including, note 17.

However, note 15, that is "Statistics and Probability calculus" is not relevant for this note.
