Math operators

Mathematical operators are special symbols used to perform arithmetic operations on numerical values. These operators allow you to perform basic mathematical operations.

+  :: Addition
-  :: Subtraction
*  :: Multiplication
/  :: Division
%  :: Modulus
=  :: Equals
++ :: One Increment
-- :: One Decrement
+= :: Incrementation
-= :: Decrementation

Increment & decrement

var++;      // Set var to var + 1
var--;      // Set var to var - 1
var += 5;   // Set var to var + 5
var -= 5;   // Set var to var - 5

The + and += operator can also be used to concatenate text

var = "hi";
var += "!"; // Set var to concat var + "!"
