+    # Ruby code added below by Paul O'Hara 01/07/2017 post "We got coders" entrance test.
+    # Code below was a third attempt at an algorithm to add up prime numbers. I decided that a pure algorithm approach 
+    # would never work, and that a more precise mathematical formula - as part of my own algorithm - was needed. My first 
+    # year university maths was now rusty, so I turned to wikipedia for a formula that would work (not a trusted academic 
+    # source, but still useful in its own right). The algorithm below contains pseudo code from the following web source: 
+    # https://en.wikipedia.org/wiki/Primality_test.
+    #
+    # The pseudo code from the above wiki source is as follows:
+    #     
+    #   function is_prime(n)
+    #   if n ≤ 1
+    #       return false
+    #   else if n ≤ 3
+    #       return true
+    #   else if n mod 2 = 0 or n mod 3 = 0
+    #      return false
+    #   let i ← 5
+    #   while i * i ≤ n
+    #       if n mod i = 0 or n mod (i + 2) = 0
+    #           return false
+    #       i ← i + 6
+    #   return true
+    #
+    # Hence, the ruby algorithm below implements this formula to identify and add up prime numbers - to the value determined by var limit.
