What is negative?

What Does negative Mean

The dictionary of the Royal Spanish Academy ( RAE ) recognizes more than a dozen meanings of negative , a term that comes from the Latin word negatīvus . The first meaning refers to that linked to denial : the act and result of denying or rejecting, or the lack or absence of something.

Negative can refer to the non-existence or lack of some element or substance . Let us suppose that the police carry out a search in a house in search of the revolver with which a crime was committed . If after the procedure the weapon in question is not found, it will be said that the result of the search was negative .

Similarly, an anti-doping or anti-doping test that is negative is a test where no substance of prohibited consumption was found. On the other hand, in a positive analysis, some illegal drugs were found .
A negative individual , on the other hand, is pessimistic and tends to observe only the troublesome. One who, about to go on vacation , talks about the risks of accidents when traveling, comments on the possibility of bad weather in the coming days and laments the chance that he will not have enough money to enjoy at his destination , it can be mentioned as someone negative.
Something negative is also harmful or harmful . For example : "Smoking is a negative habit that causes multiple health problems" , "Marcos has this negative habit of eating in a hurry" , "That the owner of the company is accused of exercising gender violence against his wife is negative for the company ” .
A negative number , meanwhile, has a value less than zero and affects positive numbers in different ways depending on the operations performed with them. In the first place, it should be mentioned that with zero it can have an identical relationship to that of positives: if -4 is multiplied by 0, it gives 0, as does 4 by 0; dividing a negative number or a positive number by zero produces the same absence of result, since zero does not have a multiplicative inverse (a number that gives 1 as a result of multiplying by it; for example: 1/5 x 5 = 1).
In the addition operation, on the other hand, a negative number plus a positive number produces an effect equivalent to subtraction, since its "inverse" nature, so to speak, tends to drive it toward zero. For example: while 4 + 3 is 7, 4 + -3 is 1, because adding a negative is equal to subtracting its modulus (also known as an absolute value , the modulus of a real number is the value that ignores its sign, and is always positive).

The multiplication and division between positive and negative numbers have similar effects. At first, if we are faced with one of these operations, we must ignore the sign and just apply it to the result; if it is a simple count, between a negative and a positive one, the result will always be negative. Let's look at two simple examples: -3 x 6 = -18; -16 / 4 = -4. If all the numbers were positive, the results would be 16 and 4 , respectively.
A photographic negative , finally, is an image that reproduces the dark and light inverted form with respect to reality . In the case of traditional photography, which today we can call «analog», as opposed to «digital», the negative is the first way in which we approach the result of our shots, since we depend on the known process as developed to appreciate the photographs as we conceive them in our imagination. On the other hand, the negative is an effect that we can achieve by using a digital image editing tool for aesthetic purposes or to cause a certain impact on a design work.
