title: How to calculate the sum of 2 numbers with BrainFuck
body: <p>I'm trying to write a program with BrainFuck that can read two numbers up to 9, calculate the sum of them and then print the result out, e.g. 3 &amp; 5 give the result 8 . </p>
  
  <p>I'm just trying to understand the BF language but it looks much harder than I thought it would be.</p>
