-	Subtraction	X = 2 5-x	3
*	Multiplication	X = 4 X * 5	20
/	Division	15/5 5/2	3 2.5
%	Modulus (pision remainder)	5% 2 10% 8 10% 2	1 2 0
++	Increment	X = 5 X ++	X = 6
-	Decrement	X = 5 X-	X = 4

Value assignment operator

=	X = y	X = y
+ =	X + = y	X = x + y
-=	X-= y	X = x-y
* =	X * = y	X = x * y
/=	X/= y	X = x/y
. =	X. = y	X = x. y
% =	X % = y	X = x % y

Comparison Operators

=	Is equal	5 = 8 returns false
! =	Is not equal	5! = 8 returns true
>	Is greater	5> 8 returns false
<	Is less	5 <8 returns true
> =	Is greater than or equal	5> = 8 returns false
<=	Is less than or equal	5 <= 8 returns true

Logical operators

Operator	Description	Example
&&	And	X = 6 Y = 3 (x <10 & y> 1) returns true
|	Or	X = 6 Y = 3 (x = 5 | y = 5) returns false
!	Not	X = 6 Y = 3! (X = y) returns true
