This research problem wherein the topic is about Carousel Numbers is under the field of Number Theory and Algebra. Number Theory is a branch of pure Mathematics wherein it deals about properties of numbers and particularly of integers. This has specific subareas which leads to what course does the topic really belong and here, it is under the Algebraic Number Theory. The Number Theory is also called arithmetic or higher arithmetic but because of some people just used these terms, so others considered now to use Number Theory. This is the oldest branch from mathematics and the widest one also for it has many branches else that can make your topic more specific from where it belongs.
Algebra is also a branch of Mathematics that talks about structure, relation and quantity. This is also one of the main branches of Mathematics for it has many subareas that talks about relationship of numbers to each other. Since this research is not for elementary students, then we can tell that this is under secondary algebra which according to the word, it is for secondary or high school students. It also talks about set elements, symbols and variables. In the case of Carousel Numbers, it may talk about elements for we need much trials in order to classify or set them in one group, which are the numbers rotating of their products if any n is multiplied on it.
Since Algebraic Number Theory falls in this research, then that means that numbers here are falling under integers. The Galois theory, group cohomology, class field theory, group representations and L-functions. Those theories that falls under Algebraic Number Theory is also an area which is open for the Carousel Numbers. Carousel numbers are not that significant in other people but for those who knows how to analyze everything in this world and with the each person’s patience, then people can also do this kind of work. In terms of applications, this can be used as topics in all secondary schools in the world for this may be a confusing and hard-time topic for each students which will explore their knowledge about numbers.
Carousel numbers are those numbers in such that if n is divided to 1, as in 1/n, then the number of periods or the numbers where it will repeat at the other time is n-1. Many already tried to do this but maybe they can’t finish too many numbers to try. Some of their reasons is that it is too difficult to use long hand division as the numbers increasing. If a researcher has a program that will make computations easier, it will not be difficult for him to pursue this but since only few can do this and others are not continuing it anymore, then this researcher may be done by me. Limitations, of course, are included for it will take much time to the researcher to do this in a rush. It can be done for a long time that will make for him easier to analyze with the numbers.
Carousel numbers maybe partial or not depending on the products that will appear if the process is done. It is not partial if all of the periods, when multiplied to any number will just rotate and rotate. It is partial if not all of the products in the carousel numbers are rotating and only chosen numbers that will be divided to the period will make it carousel numbers. Furthermore, the researcher analyzes of the numbers that will be belonging to carousel numbers. Either partial or not, at least the definition was proven already that it is rotating.
