title: Converting array of letters to lowercase
body: <p>This should take the the letter convert it to it's ASCII value then add all the ASCII values of the letters in the array together and then convert it back into a lowercase letter. The condition is just to check if it goes past 122 aka z. The <code>Write-Host</code> statements are just for figuring out whats wrong. </p>
  
  <pre><code>$t=@('a','b','c')
  $y=0
    foreach ($x in $letters) {
      #write-host $x
      $y=+ [byte][int]$x
      write-host $y
      if ($y -gt 122) {
         $y= $y - 24
   }
   }
   $z=[char]$y
   write-host $z
  </code></pre>
