title: Which particular software development tasks have you used math for? And which branch of math did you use?
body: <p>I'm not looking for a general discussion on <a href="https://stackoverflow.com/questions/157354/is-mathematics-necessary-for-programming">if math is important or not for programming</a>. </p>
  
  <p>Instead I'm looking for real world scenarios where you have actually used some branch of math to solve some particular problem during your career as a software developer.</p>
  
  <p>In particular, I'm looking for concrete examples. </p>
