Basic Calculator

Hello All, Currently studying an IT course and just need help creating a calculator for a project i am doing. It's a quite basic calculator that needs to contain numbers (0 to 9) including a decimal point (.), addition (+) and subtraction (-) buttons. Also There should be Total, Delete, Clear and Exit Buttons. I also have to calculate tax, The Tax should be calculated on the amount purchased and should be added to the subtotal to calculate the total for the user. Tax percentage is fixed as 10% on the amount spend by thecustomer. Numeric buttons: The event handlers for each of these Button’s click event should concatenate the proper value to the TextBox. + and - buttons: The event handler for these Button’s click event should take the value displayed in the Subtotal: field and the value displayed in the upper Text Box and perform the operation of the clicked button. The result should be displayed in the Subtotal: field. The Total Button: The even handler for this Button’s click event should use the subtotal to calculate and display the tax and total. The Delete Button: The event handler for this Button’s Click event should clear only the data in the TextBox. Can only be to these specifications, otherwise looking at failing The Clear Button: The event handler for the Buttons click event should clear the user input and display the value $0.00 for the subtotal, tax and total. The Exit Button: The event handler for this Button’s click event should exit the application. Hopefully someone can help me as im doing a course that involves programming and really dont want to enter into it as a job field ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
