15. Arithmetic Operators
Operators Description
+ Adds the two operands
- Subtract the second operand from the first
* Multiplies the operands
/ Divides the first operand by second operand
% Divides first operand by second operand & returns remainder

16. Relational Operators
Operators Description
== Returns true, if operands are equal. Else returns false
!= Returns true, if both operands are not equal, else false
> Returns true, if first operand is greater, else false
< Returns true, if first operand is lesser, else false
>= Returns true, if first operand is greater or equal, else false
<= Returns true, if first operand is lesser or equal, else false
