Natural numbers and random numbers.

A random number ("al azar" or "aleatorio" in Spanish) is a number in a sequence whose value is unpredictable. In other words, it is the number that has the same probability of being chosen and that the choice of one does not depend on the choice of the other. Random numbers are used in everyday life in games of chance, contests, lotteries, computer animations, cryptography etc. There are randomization studies on the numbers that humans produce thinking that we do it completely randomly, but it is not like that. Humans are very bad at giving random numbers, because there are clear tendencies in humans for the elaboration of skewed sequences and they are related to personal characteristics, previous knowledge or information, etc.

The natural numbers are the first to appear in different civilizations. They allow us to count the elements that are in a set (cardinal number), express the position or order that an element occupies in a set (ordinal number) and identify (differentiate) the different elements of a set. They have no decimals, they are not fractional, and they are always to the right of zero on the real line. They start from one and are infinite. The 1, 2, 3, 4, ... are examples of natural numbers. Whole numbers are like natural numbers, but negative numbers and zero are included. They also do not have decimals and are not fractional.
Positive integers are placed to the right of the number zero on the number line and negative integers are placed to the left of the number zero. So an integer can be negative (-1, -2, -3,…), positive (1, 2, 3, 4, 5,…), or zero (0). Natural numbers 0 1 2 3 4 5 6 7 8 9
