Standard Calculator

Task: Write a windows application in Visual Basic to perform functions of a standard calculator

Description: Figure 1 shows standard calculator that comes with the Windows 7 operating system. The calculator allows a user to eater numeric values via the 0.9 keysibuttoas. Arithmetic functions such as. add. subtract. multiply. and divide can then be performed on the numeric data. Details of the arithmetic functions are shown in Table 1. Write a Windows application in VB to mimics the Windows 7 calculator. Use text box controls to display the operation being performed and the resulting answer. Sample screen shot of your calculator is shown in Figure 2.

Function	Button	Points	Description
1	End	2	End the program
2	C	2	Clean all values
3	CE	2	Clears the number displayed in the textbox
4	MC	2	Clean the number stored in memory
5	MR	2
5	MR	2	Recalls the number stored in memory. The number remains in memory
6	MS	2	Stores the displayed number in memory
7	M+	2	Adds the displayed number to the number in memory
8	M-	2	Subtracts the displayed number from the number in memory
9	M	2	Displays red background when a number is in memory
10	0-9	2	Enters digits 0-9 and "."
11	/	5	Divides the previous number by the displayed number
12	¹¹	5	Multiplies the previous number by the displayed number
13	-	5	Subtracts the previous number from the displayed number
14	+	5	Adds the previous number to the displayed number
15	+/-	5	Changes the sign of the displayed number
16	sqn	5	Calculates the square root of the displayed number
17	St	5	Enter a number. click an operator (+, -. . or)). enter the second number. click %. and then click =. For example. 100 + 10% = 110. 100-10%=90. 10010%=1000. and 100/10b= 10
