I'll take a shot at it...

I see the Math Papyri as being copies of completed tests, with both the questions and answers on them.
That, imho, is why some of the answers don't seem to make sense.

If you were to go to any high school, and collect ungraded tests, saving just a few, put them away for 3,300 years, and then look at them, the wrong answers may be more intriguing than the right ones, aye?

Thus some inclusive answers that appear to indicate deep dark secret knowledge may be some student blowing it.

And no, I can't prove my theory any more than you can prove yours, thus they remain interesting hypotheses for now...
