one half of one half is a quarter

That depends on what you're multiplying.

i what sense?

Less than the sound of one hand clapping?
No, sorry, that was flippant. Here's how to work it out:
I I I I I^2
---- ---- = ----- = ----- = I^(2-4)
II II II II I^4
... and since unity raised to any power at all is unity,
the answer is one.

In the sense that different kinds of objects use different rules
for multiplication.
(1/2) * (1/2) = 0
(0.5) * (0.5) = 0.25

Maybe, but for us in more advanced nations, the question was asked on
the 2nd!

so the answer is still 42.

Eric, you missed the second half of the solution. Out of symmetry
considerations the solution could as easily have been i^2 == -1. A
plausible equiprobabilty would yield the the superposition state as
.5(1) + .5(-1) = 0, which is clearly consistent with the one-hand clap.

Absolutely.

Nope, that's zero times zero. Fortunately it equals zero as expected.

A very conventional answer. I prefer half times half being three,
as half a dozen times half a dozen is three dozen.

It's 1/4 of a square dozen (which is 3 dozen as you say).

I double-checked, using units in the complex plane, and (1,half)
times (1,half) was (1,one).
In summary, I'm now divided as to what it should be.

I get (0.75, one).

I'm betting you didn't start with units, which would
explain why you didn't finish with a unit either. I'm in
(r, theta) notation, not (x, y).
