CCCC hints: 1. This is not an &lit - the clue has a definition part and a wordplay part, not necessarily in that order. 2. Charades. 3. Someone has already said one part of the intended wordplay in this chat... 4. A Bible scholar might have an advantage here...

Ah! "of" = "Ordinary Form" of course.

@Stiv the fact that "end of" is an indicator didn't help :-)

Yeah, that was fun to include :)

Let $n$ be an integer. $n$ logicians standing in a circle are blindfolded and a hat of either red or blue is put on each person's head. Blindfolds are then removed and each person can now see everybody's hat color but her own. No communication in any form is allowed after the hats have been place...

Find distinct integers $a$, $b$, $c$ and $d$ such that $\frac{1}{a}+\frac{1}{b}+\frac{1}{c}-\frac{1}{d} = \frac{1}{a} * \frac{1}{b} * \frac{1}{c} * -\frac{1}{d}$ No calculators or computers allowed.

Can you find distinct positive integers $a_1, a_2, \ldots, a_{n-1}, a_n$ for any $n$ such that $$-\frac{1}{a_1}+\frac{1}{a_2}+\ldots+\frac{1}{a_{n-1}}+\frac{1}{a_n} = -\frac{1}{a_1} \cdot \frac{1}{a_2} \cdot \ldots \cdot \frac{1}{a_{n-1}} \cdot \frac{1}{a_n}$$ The previous puzzle shows that a sol...
