Arithmetic, Logical And Comparison Operation

Here, Dot(.) is used to concate the statements. <br> tag is used to break the line.

OutPut

Value of a = 10
Value of b = 20

***Arithmetic Operator*** 
Addition of 10 and 20 = 30
Subtraction of 10 and 20 = -10
Multiplication of 10 and 20 = 200
Division of 10 and 20 = 0.5

***Comparison Operator*** 
10 is less then 20 

***Logical Operator*** 
10 is between 0 and 50
