Solution:

1. It's really just a math problem, not about javascript.
2. Calculation:

   foo = 5 + 6 * 7 = 47
   bar = foo % 8 = 47 % 8 = 7
   moo = bar * 2 = 7 * 2 = 14
   rar = moo / 3 = 14 / 3 = 4

3. The IF statement below give us a hint.

   if (x.length == moo)

4. So, just input something where its length is equal to 14. 
5. It's done.
