Lab 2.1 - Calculator

Calculators have been around for a long time. In fact, if you know anything about the history of computers, you know that the first computers were really just calculators.

Create a Calculator application. The program should take as input two numerical values. Then, the user chooses one of the six calculation buttons on the form, and the program displays the answer.

Confused? Here's some help. You will need the following objects:
• A TextBox for the first value.
• A TextBox for the second value.
• Six (6) Buttons, one each for +, - , *, /, \, and Mod.
• A Label to display the result.

Test your program using the values 23 and 7. Your answers for each button (in the order given above) should be 30, 16, 161, 3.28571429, 3, and 2.

Common mistakes include:
• Not setting the TextAlign property to Right in TextBoxes intended for numeric input.
• Not leaving enough room for the full answer to appear.
• Wasting real estate on the form.
• Cutting off the title on the form by making it too small.

As always, design a useful and proper interface.
