title: Making a list of odd numbers from a list
body: <p>I need to take odd numbers from a given list of integers to create another list.
  I have written an <code>isOdd</code> function, but couldn't make the rest work.</p>
  
  <pre><code>isOdd :: Integer -&gt; Bool
  isOdd n = rem (abs(n)) 2 ==1 
  
  takeOdds :: [Int] -&gt; [Int]
  ...
  </code></pre>
