I'm posting one puzzle, riddle, math, or statistical problem a day. Try to answer each one and post your answers in the comments section. I'll post the answer the next day. Even if you have the same answer as someone else, feel free to put up your answer, too!
Going along each row, the fourth number is the sum of the first and third numbers, minus the second number. So for each row we have: 9 + 6 - 4 = 11 3 + 7 - 6 = 4 5 + 4 - 8 = 1 11 + 3 - 6 = 8
The same pattern holds going down the columns: 9 + 5 - 3 = 11 4 + 8 - 6 = 6 6 + 4 - 7 = 3 11 + 1 - 4 = 8
I would have said take the first and third number and add it to get get the same number as when you add the second and fourth number. This is true across each column and each row. For instance in the first row, 9+6 = 15; 4+11 =15.

You have the pattern down and the answer is 8.
