title: How to find modulo of a sum of numbers?
body: <p>I am seeking for a way to find modulo of a sequence of numbers like:
  (a1 + a2 + a3 + a4 + ... + an) mod x</p>
  
  <p>Is there any way/property of modulo function so that I can compute mod of this sequence from the individual mods of numbers in sequence.</p>
