The answer is 19. That doesn't change because some idiot got most of the others wrong.
A 9/18 wrinkle in reply to the simple addition '19' folks. What if the problem was changed to...
1 + 4 = 5
2 + 5 = 7
3 + 6 = 10
8 + 11 = ?
My solution: 20
Just simple addition. All numbers base-9.
I was hoping to get the simple addition folks to start exercising their "little gray cells." But, I know, base-9 is un-'merican.
It's fascinating watching how various people have approached reconciling these mathematical statements. It's easy to see how politics, religion, etc. become disparate. There are those that make an effort to hold the statements as true and somehow reconcile them; those that discard information/statements they don't recognize as true; some random responders; and then there are those that seem to only and always be thinking about one thing.
