Master the manipulation and computation of integers of any signs
Enroll in Course
The aim of that course is to give you the mastery of the construction and manipulation of the integers of any signs.
Starting with practical animated graphics, and Python manipulations, you will become by the end of that course a master in:
 Constructing the integers set, from negative infinity to positive infinity
 Comparing integers of any signs, and ordering the integers set Z
 Adding, subtracting and multiplying the integers of any signs, including doing all these operations in a unique formula.
 Exponentiating the integers of any signs by natural integers
 Comparing the results of additions and/or subtractions.
 Comparing the results of multiplications and/or exponentiations.
