+   Addition        Adds together two values            x + y   

-   Subtraction     Subtracts one value from another    x - y   

*   Multiplication  Multiplies two values               x * y   

/   Division        Divides one value from another      x / y   

%   Modulus         Returns the division remainder      x % y   

++  Increment       Increases the value by 1            ++x or x++

--  Decrement       Decreases the value by 1            --x or x--
