+## Full List of Operators
+
+The following mathematical operators are available. A definition is omitted here, as they are commonly used in most programming languages.
+
+```
++  -  *  /  %  +=  -=  *=  /=  %=  ++(prefix)  --(prefix)  (postfix)++  (postfix)--
+```
+
+Likewise, the following logical operators are available (`&&` is more tightly bound than `||` due to historical reasons):
+
+```
+(  )  [  ]  {  }  !  !=  ==  <  >  <=  >=  &&  ||
+```
+
+Other operators used throughout the language are: the assignment, colon, semicolon, comma, dot and rest operators:
+
+```
+= : ; , . ...
+```
