                 Performing Operations on Variables

                  aria le is a storage area   hich defines the si e  layout  range set o  operations to  e per ormed
                 on variable.
                 Once you declare the data types, you will learn to perform the operations on the data types.

                   Operator: It is a symbol which operates on a value assigned to a variable. Example: +,-, *, \.

                   Operand: It is a value on which the operator performed operation.
                 Arithmetic Operators

                 Arithmetic operation combines two or more numeric expressions by using the arithmetic operators.
                 The arithmetic operators perform operations such as: addition, subtraction, multiplication, division,
                 and modulus. In the table given below, we are taking, value of variable a= 10, and of b=30.

                    Operation        Symbol                        Description                         Example


                  Addition              +        Adds one operand to the other                     a+b= 40


                  Subtraction           -         u tracts second operand  rom the first           a-b= 20


                  Multiplication        *        Multiplies one operand by the second              a*b=  300


                  Division              /         i ides first operand  y the second               b/a= 3


                  Modulus               %         i ides  the  first  operand   y  the  second   and  b%a= 0
                                                 returns the remainder

                  Increment             ++       Increases the integer value by 1                  a++ = 11


                  Decrement             --       Decreases the integer value by 1                  b-- = 29



                 Assignment operators
                 An assignment operator assigns a new value to a variable.
                 In the table given below, we are taking, value of variable a=10, and b=30.
