title: Reading in numbers, then adding them in a loop. Bash/Linux
body: <p>Help!</p>
  
  <p>I am having big problems finding out how to add numbers that i've written in(read) a loop.
  The task im supposed to do is to add X amount of numbers(which I must use read for) then adding them all when "Ctrl+d" is pressed. Im fairly new to linux so please make it as simple as possible :)</p>
