Man, I'm so stupid! :P
It's not 815 = 4+8+15+16+23+42
It's 108 = 4+8+15+16+23+42
Sorry! :P
But 815 also is 8 and 15! And 8+15 = 23
Man, these writers really did their math! :P

Episode 3.7:Not In Portland
Juliet says she has been on the island for 3 years 2 months and 28 days.
(2 + 8) - (3 * 2) = 4
--> 8
(2+ 8) + 3 + 2 = 15
(2 + 8) + (3 * 2) = 16
28 - 3 - 2 = 23
(28 * 3) / 2 = 42
