A class is written which has different functions to perform the different mathematical operations depending upon the input provided the mathematical operation is performed on the two operands which are taken as input for each function,  the class which is written below is the child class of the test case class from the unit test module, with the help of this parenting test case class we were able to use various inbuilt functions of the test case class which help us to write various test case function to test the mathematical results which are calculated by the various function written inside this class
