# ScientificMemCalc

In this assignment, you will write a subclass of the MemoryCalc class from Assignment 6. This new
calculator, called ScientificMemCalc, should be able to do everything that the MemoryCalc could do,
plus raise the current value to a power and compute the natural logarithm of the current value. This is a
fairly realistic assignment – often when you are working for a company, you will be asked to make
minor extensions to existing code.
You will need to override the displayMenu method to add the new options. Be sure to only add code to
the ScientificMemCalc class if it is necessary – leverage the code from the base MemoryCalc class
whenever possible. Use the power of inheritance to do this rather than cutting and pasting or otherwise
duplicating the code. Finally, write a new class called ScientificCalcDriver that shows the functionality
of your new class. This will be very similar to the CalcDriver class contained in the assignment9.jar
file.
