On having developed any program, we use normally operators who serve to us to realize diverse operations that grant him a certain complexity grade to our programs, since, otherwise the program would always realize the same and therefore it would not be a useful program.

Arithmetical operators
+	It adds two values
-	It reduces two values (or a value goes on to negative)
*	It multiplies two values
/	It divides two values
%	I remain of dividing two values
++	I increase in a unit
--	Decrease in a unit

Allocation operators
=	It assigns to the right part the left value
+=	It realizes the sum of the right with the left and assigns it to the right
-=	It realizes the subtraction of the right with the left and assigns it to the right
*=	It realizes the multiplication of the right with the left and assigns it to the right
/ =	It realizes the division of the right with the left and assigns it to the right
%=	The rest is obtained and it is assigned
.=	Concatena the value of the left with the right and it assigns it to the right

Logical operators
!	Operator not or denial. If it was true a raisin to false and vice versa
and	Operator Y, if both are real costs really
or	Operator O, costs really if some of the two is real
xor	Real if some of the two is true but never both
&&	True if both it are
||	True if someone it is

Conditional operators
==	He verifies if two numbers are equal
! =	He verifies if two numbers are different
>	Major that, he is sick true in affirmative case
<	Minor that, he is sick true in affirmative case
> =	Major or equal
<=	Minor or equal
