# Construct and compare the (Signed) Integers

## Discover the negative numbers

That course will let you discover the negative integers, that form, with the natural integers set N, the (signed) integrs set Z.

These are the numbers we use to estimate the difference between any two natural integers, for instance to calculate the balance of an accountancy table.

By the end of that course, you will be able to compare two integers of any signs, and to order a list of them

You will also be ready for the rest of our series about Practical Mathematics, the math that are taught from a practical point of view, based on Python coding sessions, and bringing you from arithmetics and number theory up to Calculus.

To enter that course, it is recommended to have followed the “Natural Integers MasterClass"..

There are two main sections, one with the construction of the (signed) integers set, beginning with the negative integers discovery and the second one that structures the (signed) integers set Z as an increasing sequence from minus to plus infinity.

And, last but not least, you will become the owner of a downloadable recapitulative documents, with the knowledge given by the videos fixed as rigorously proven theorems.

## Your Instructor

Fabienne holds the Agregation in Mathematics, the highest French diploma to teach mathematics in secondary schools. After a 26-year career as an R&D engineer in applied mathematics, she founded Mathedu (Mathematics Re-engineering) with her husband and collaborator Francois, to teach mathematics from a practical point of view, based on Python programming. She is both an expert in mathematics education and a passionate woman who will help you experience the joy of improving your mastery of mathematics.
