The Latin word *positivus* came to our **language** as **positive** . It is an adjective with multiple uses according to the context. It can be, for example, something that results **affirmative** and **unequivocal** : *"The anti-doping control tested the Russian tennis player positive: the presence of ephedrine was detected in his urine"*, *“My vote is positive: I am in favor of the reform of this law”*, *“The boss gave me a positive response so, starting tomorrow, I will change my work shift”*.

**Positive** , on the other hand, is what it is **Okay** , **cash** or **Useful** : *“The first meeting with the Japanese was positive: hopefully we can reach an agreement”*, *"I think the tournament is being positive for the team because we already won more games than last year."*, *“María always tells me that it is not positive that she reacts in this way, but I cannot help it”*.

When a **person** is rated positive, it will be referring to what is **optimistic** and always try to look at the bright side of things: *"I am a very positive man, I do not like to waste time worrying about the bad"*, *"I'm going to think positive and make strength so that the operation goes well"*, *"I don't understand how you can be positive at such a time"*.

In this sense, the positive term can function as a synonym for "optimistic", since it describes the constructive attitude towards problems or obstacles, the look that looks for potential **solutions** instead of unnecessarily highlighting what cannot be repaired. The opposite is a pessimistic person, although sometimes someone realist of pessimism is accused, simply for accepting the problems instead of trying to deny them.

In the field of **math** , a number is positive when it is greater than **0** (and therefore not negative): 3, 8, 125 and 8680 are positive numbers. The applications in this case are many, since several types of numbers can be positive or negative, such as integers and rational ones.

Usually, when you talk about positive numbers you have the idea of "moving forward" along a **axis** Cartesian, while with the negatives the exact opposite is plotted. In other words, if we have the point (4.2), where 4 corresponds to the position on the X axis and 2 to that of the Y axis, and we say that it advances 4 units in X, this is interpreted as the sum of 4 to the value of X, that is, as a positive displacement along the X axis.

This is how people think, for example, **movement** of objects and characters in the virtual worlds of movies and video games. Thus, in a racing game, for example, it is sought to align the cars in such a way that their progress along the tracks corresponds to a sum along their horizontal axes.

Of course, in this case there is a more complex situation than that of a simple graph on a blackboard: the axes of each object are not always perfectly aligned with those of the world; In fact, they rarely are. Therefore, a distinction is made between "local space" and "global"; in this way, a movement that for an object can mean a **translation** positive on your local X axis, you can also carry a subtraction on the global X axis.

The **positive electrical charge** Finally, it is the kind of **load** what do the **protons** (unlike electrons, which have a negative charge).
