title: How to subtract 1 number multiple times and put on new list?
body: <p><em>Edit</em>: thanks for the fkn -3 downvotes, this is really going to encourage ameteurs like me into getting into c#, im sorry im not a fkn expert with a phd in computer science, i thought this forum/website was about engaging in a community and work together to learn new things while being helped/tutored by other people that love this field, boy was i wrong, this forums is just filled with hatred for people like me, i guess i will try to find another forum that's not so unforgiving.</p>
  
  <p>This program grabs a number from a list (9.9) and in a new list im having trouble subtracting it by 2 so that in my 'for' loop it add's a list of 5 numbers.</p>
  
  <pre><code>for (int i = 0; i &lt; 5; i++)
    {
       rList2.Add(9.9 - 2);
    }
  </code></pre>
  
  <p>But here's the problem, the new list's contents are:</p>
  
  <pre><code>7.9
  
  7.9
  
  7.9
  
  7.9
  
  7.9
  </code></pre>
  
  <p>when it should be:</p>
  
  <pre><code>9.9
  
  7.9
  
  5.9
  
  3.9
  
  1.9
  </code></pre>
  
  <p>Wondering what I'm doing wrong :/</p>
  
  <p>Summary: need a function that subtracts 1 number (9.9) by itself by 2, 5 times.</p>
