Statistical Calculator

Task: Write a windows application in Visual Basic to perform functions of standard and statistical calculators.

Description: The standard calculator should work as described in project #1 . The statistical calculator should operate similar to the Windows 7 statistical calculator. The user should be able to go back and forth between the two calculators via the View command. The text box should display the number entered and the calculated result. Button M should display "Nr if data is stored in memory. Button "F-E' should flip number display format between "F" and "E". Data should be displayed in two column list view control. All formula based computations should be performed by a Sub or a Function, and placed in a module. Figure I shows sample screen shot of a statistical calculator. Figure 2 shows the windows 7 statistical calculator.
