2+2x4
I suck terribly at maths but when I worked this out I got 16. But apparently most people say it's 10. It's on a Facebook meme thing. People are saying that only idiots think it's 16.
I worked it out as 2+2=4, times 4 by 4 and you get 16.
Do you guys make 10 or 16?

You are supposed to do the multiplication first, then the addition. This is how most people get 10. Parenthesis can be used to change the order of operation.

10 = 2 + (2 x 4)
Order of Precedence dictates that higher-order math functions (division, multiplication) are performed before lower-ordered ones (addition, subtraction).
And no, this is not a "Facebook meme thing"; this is standard mathematical practice.
