conversations.value: Ed and Jacob already had 2 shells in their shell collection. Then they went to the beach to collect even more. Ed found 7 limpet shells, 2 oyster shells, and 4 conch shells. Jacob found 2 more shells than Ed did. How many shells do the pair have altogether?
  Give me a solution to this problem

conversations.value: Ed found 7 shells + 2 shells + 4 shells = 13 shells at the beach.
  Jacob found 13 shells + 2 shells = 15 shells at the beach.
  In total Ed and Jacob have 2 shells + 13 shells + 15 shells = 30 shells.
