title: RegEx: How can I match all numbers greater than 49?
body: <p>I'm somewhat new to regular expressions and am writing validation for a quantity field where regular expressions <strong>need</strong> to be used.</p>
  
  <p>How can I match all numbers greater than or equal to 50?</p>
  
  <p>I tried</p>
  
  <pre>
  [5-9][0-9]+
  </pre>
  
  <p>but that only matches 50-99. Is there a simple way to match all possible numbers greater than 49? (only integers are used)</p>
