1. Introduction
The theory helps to obtain information about whether the result is even or odd, as well as to obtain information about whether the origins are even or odd. therefore, based on the meaning of mathematics that accurately describes the real world and through representations of an element or fact that are linked to space, thus, using the relationships between spaces it is possible to understand even and odd numbers. This study presents a possible model for understanding formations.
Note: The study uses a rescue diagram developed by John Venn.
2. Math Sense
The knowledge of mathematics today is not the same as it was at the beginning of the history of mathematics, because in the trajectory of thousands of years ago there was an evolution in the knowledge of mathematics, just as in the future of mathematics thousands of years ago will continue to evolve its knowledge, with the aim of describing the world with rigor and precision.
The first signs of knowledge of mathematics occurred due to the need to represent elements, giving rise to mathematics that emerged in Ancient Egypt and the Babylonian Empire, around 3500 BC. However, in prehistoric times, human beings already used the concepts to count and measure. An example of the first elements to represent were stones and sheep, where each stone represented a sheep. An example if there were 15 stones and because there were also 15 sheep, in this case two stones are missing during the count and because there are also two sheep missing. This need to represent the elements in the case of sheep arose with the aim of avoiding losses of sheep, that is, avoiding losses.
The emergence of the representation of elements aims to describe the world with rigor and precision. Many people benefit from mathematics because mathematics makes life easier for everyone, as is the case with the sheep counter who, because of mathematics, did not suffer any harm.
Therefore, based on the meaning of mathematics, it is possible to state that mathematics is related to physical spaces.
3. The Use of Mathematics in Everything
Furthermore, mathematics is used in many things, such as probability, which analyzes the possibility of an event occurring. Percentage is used to compare quantities, profits, discounts and losses. Geometry is present in traffic signs, houses and buildings. The quadratic or 2-degree function is used to calculate projectile launches and motions. Set theory helps determine the number of respondents and their groups. The exponential function explains radioactive decay and ecological and sociological growth.
4. Detailed Examples of Mathematical Usage
Example 01: A group of friends made up of 8 people goes to eat at a pizzeria, where they buy 2 pizzas of 8 slices each, that is, 16 slices in total. When the two pizzas arrive, one of the friends tries to get everyone to eat the same number of slices, so the division calculation was made: if the total is 16 slices and there are 8 people to eat, each person can eat 2 slices equally each one.
In this case, the division is calculated so that none of the 8 friends eats more or less than any member of the group, the division arises to maintain equality.
Example 02: In research there is an intense presence of mathematics in their work. A survey, for example, aims to understand the profile of crime in Brazil, that is, characteristics of crime. The numbers indicate the reality of crime in Brazil: poorer regions have more violence, richer regions have less violence.
In this case, it is up to public policies to act in the poorest regions, through the implementation of opportunities for people to escape poverty. All this because numbers present information and from that it is possible to deduce solutions.
Example 03: Mathematics is strongly linked to health, as numbers indicate information that may be contained in food products or medical tests. The information, through numbers, can tell you the ideal amount of consumption or not of this food. Additionally, medical exams can diagnose illnesses. If so, numbers can help humanity stay healthy.
Example 04: Numbers can help with people’s safety, showing limits for people in elevators, boats, planes and cars. The limits are known through a study with numbers. Furthermore, the numbers indicate the speed limit of a means of transport.
Example 05: The existence of commerce depends on mathematics, as the product that commerce sells has a value, but the value can be changed as you seek the ideal profit from the product.
In this case, knowledge of the number is essential to know the value of a product, to obtain the desired profit.
In general, mathematics is present in everything, that is, in any physical space, because it arose from the need to describe the world with rigor and precision.
5. Even and Odd Numbers
An even number is a whole number that is divisible by 2 without a remainder (ex: 2, 4 and 6), and an odd number is a number that is not divisible by 2 without a remainder (ex: 1, 3 and 5).

8. Lógica em Números Maiores
Exemplo 01: 3+3+3+3+8+4=24
Se o número 24 for par, é possível saber as origens apenas mantendo o número par e depois encontrando a quantidade certa de divisão para cada termo existente. Observe que as origens têm quatro números ímpares e dois números pares.
ABCDEFGH deve ser mantido aos pares, ou seja, em duas partes iguais: ABCD e EFGH (correto).
ABCDEFGH= A+B+C+D+EF+GH, ou seja, além de manter o resultado par, foi possível dividir seis (6) termos das origens.
Exemplo 02: 4+6+9+3+1 = 23
Se o número 23 for ímpar, é possível saber as origens apenas mantendo o número ímpar e depois encontrando a quantidade certa de divisão para cada termo existente. Observe que as origens têm três ímpares e duas pares.
ABCDEFG é necessário manter as partes ímpares, ou seja, partes desiguais: ABCD e EfG
ABCDEFG= AB+CD+E+F+G, ou seja, além de manter o resultado ímpar, foi possível dividir as origens em 5 (cinco) termos.
9. Conclusion
Therefore, the theory that states that spaces related to each other provide numerical knowledge is observable and coherent based on the meaning of mathematics that interacts with spaces. The study aims to present a model for understanding numerical formations.
