Using jQuery I'd like to create a game that outputs random number 1 - 20 and then when I drag the plus "+" or "-" symbol to the drop zone calculates the two random numbers (e.g. 3 + 5 = 8) I have searched google for tutorials that may help me accomplish this but i've only come across shopping cart tutorials that add items with the same price not random numbers. Can anyone provide a url to tutorials that can help me accomplish this goal or provide me with an example?

Thank you in advance.
