The Fractions and the Rational numbers MasterClass
Scheduled for August 31, 2021
Mastering the Fractions and the Rational Numbers Construction and Manipulation
In that course, we will discover the fractions of integers, that are interesting by themselves, and the rational numbers, that are represented by fraction, but not reduced to fractions.
This is because many fractions (an infinity in fact) reprent the same rational number.
We willl learn to add, subtract, multiply, divide and exponentiate fractions, and also rational numbers, that are families of fractions.

The Real Numbers and Approximation MasterClass
Scheduled for December 25, 2021
Mastering the Real Numbers Construction and Manipulation
In that course, we will construct the real numbers set as famiies of sequences of rational numbers, the sort of sequences called Cauchy sequences.
(The Cauchy sequences areinteresting by themselves, because they give a rigorous frame to the approximation matter.)
The addition, subtraction, multiplication, division, and exponentiation of real numbers will be comprehensively taught.

The Calculus Classes
Scheduled for 20222024
Mastering Calculus, from a numerical analysis point of view
With the real numbers set and the approximation tools, we shall be ready for the Calculus Classes:
 The systems of linear equations
 The polynomial functions
 The continuity of functions
 The diffenrentiation of functions
 The integration of functions
The particularity of these Calculus classes is that they don't only start from a practical point of view, as all our courses, but it leads also to numerical analysis, the science of algorithms.
So that you will be able to practice immediatly in Python, and to use your mastery for any scientfic computing project you may havr to develop.

More Numerical Analysis
Scheduled for 2024, 2025 and beyond
Mastering Numerical Analysis of any kind
By the end of the year 2024, you will get more classes of numerical analysis:
 Sequences and series of real numbers
 with the definition of exponential and logarithm functions
 Complex numbers with their exponential
 The polar coordinates in the plane
 The fourier transforms
 The multivariables functions with the optimisation problems
 Eigenvalues and Eigenvectors
 With the conditioning of a problem
 Differential equations of one real variable
 Two boundary values problems
 Sequences and series of real numbers
