title: C# how to detect operators in string to calculate?
body: <p>Say a program receives an input string <code>"8*10+6/2"</code> and should output <code>83</code>, in this case. how to handle the operator? </p>
  
  <p>I can chop the string into individual strings, then detect whether it is a number or operator. If it is an operator I can convert it to <code>int</code>. But I have no idea how to handle the operator so that the calculation works.</p>
