basic Maths skills?

I just read a post on Facebook with the poll: "50 + 50 x 0 + 1=?" and the available possible answers (votes results taken just now):

option	votes	%
0	3 870	1.88
1	75 529	36.70
50	1 276	0.62
51	116 153	56.44
100	1 183	0.57
101	7 788	3.78

So it seams to me that democracy still works. Even on such precise topics as basic arithmetic.
