In the array of numbers below, each number above the bottom row is equal to three times the number immediately below it. What is the value of x+y?

        27      x     81     -108
        9      -18    27     -36
        3      -6     y      -12
        1      -2     3      -4

Er...

y = 9, x = -54, x + y = -45. Not much else I can say...

Is it:

-549, because you wrote the code in JavaScript?
