Let's see...

16 = 2^{4}

= 1*2*2*2*2

= (((1<<1)<<1)<<1)<<1

In binary we'd write it as ten thousand, yet in hexadecimal it's only ten.

But in the Shakespeare Programming Language, sixteen is defined as a nice warm sunny blue sky, or perhaps the difference between nothing and my disgusting slimy greasy fat pig.

There are also sixteen tablespoons in a cup, and sixteen fluid ounces in a pint.

And if you add up the numbers one through sixteen, you get 136, which is the sixteenth triangular number.

sixteen = six + ten

Therefore, ((((s==0)&&(t==0))||((s==0)&&(e==0))||((s==0)&&(n==0))||((i==0)&&(t==0))||((i==0)&&(e==0))||((i==0)&&(n==0))||((x==0)&&(t==0))||((x==0)&&(e==0))||((x==0)&&(n==0)))^^((s!=0)&&(i!=0)&&(x!=0)&&(t!=0)&&(e!=0)&&(n!=0)))

and

if ((s==i)&&(s==x)&&(s==t)&&(s==e)&&(s==n)) then ((s!=1)&&(i!=1)&&(x!=1)&&(t!=1)&&(e!=1)&&(n!=1))

16, when a is 2 and b is 4, is one of those instances in which a^{b} equals b^{a}
