In the field of mathematics, integers are defined as all those numerical figures that make it possible to state a certain quantity with respect to the unit of said figure. Within the whole numbers, other classifications can also be found, such as rational numbers and natural numbers, within which zero and negative numbers are included, so it can be said more simply that a decimal number is that that does not have a decimal component within its structure.
For its part, a negative integer can be said to be the consequence of arithmetic operations such as addition and subtraction. The use of integers, although with different symbols, can be traced back to very ancient times, over the centuries they were given the name of integers since they represented a number of units that cannot be divided, by Some example, state, a person, an animal, countries, etc.. Already by the seventeenth century they began to be used in the work of mathematicians and scientists in Europe, however 'already during the Renaissance period some mathematical scholars such as Cardano and Tartaglia had mentioned them in some of their works on third degree equations.
Some of the uses that integers allow are to indicate the height of things, for example in the case of a mountain it can be said that it has a height of 2,500 meters above sea level. In the case of negative integers, they can be used in various ways, one of the most common to indicate temperatures below zero, that is, very cold temperatures, they are also used to indicate depths under the sea. In the case of negative numbers, it is necessary to highlight that all of them will be less than any positive number and also zero, if they are represented on the linenumerical, any number that is located to the right of zero will be greater than any that is located to the left of it.
