title: events and delegates dilemma
body: <p>I am really in a fix over understanding the concept of events and delegates.I know that delegates are the objects holding references to methods and can call methods having the same return type and parameters, but then what exactly are events?</p>
  
  <p>If I need to use events for making a simple calculator, then how can I use them so that there are 3 events: one that can be used one for digit, one for the operators and the other for the equal or the result operation.</p>
