Line 31: − + − + − Recursion in language enables phrases to be embedded within one another, usually through [[conjunctions]], such that it should be possible to make an infinitely long sentence. For one such example we could take the sentence ''Many atheists are overweight'' and precede it with ''<person> said that'' indefinitely, as follows: ''Blaine said that Barbie said that Ken said that many atheists are overweight.'' +

There's a simple procedure for finding out whether a number is divisible by three.
#If the number is 3, 6, or 9 then it's divisible by three.
#Otherwise, add all the digits of the number; if the sum of the digits is divisible by three, then so is the original number.
Examples:
* 12 => 1 + 2 = 3 (yes)
* 14 => 1 + 4 = 5 (no)
* 96 => 9 + 6 = 15; 15 => 1 + 5 = 6
