title: What do the "+n" values mean at the end of a method name in a stack trace?
body: <p>When reading a stack trace like:</p>
  
  <pre class="lang-none prettyprint-override"><code>[FormatException: Input string was not in a correct format.]
     System.Number.StringToNumber(String str, NumberStyles options, NumberBuffer&amp; number, NumberFormatInfo info, Boolean parseDecimal) +2755599
     System.Number.ParseInt32(String s, NumberStyles style, NumberFormatInfo info) +112
     System.Convert.ToInt32(String value) +68
  </code></pre>
  
  <p>What do the +68, +112, etc. numbers mean. I'm guessing that they're offsets to something. If so, what?</p>
