Morning gentlemen and gentlemen.

I would like to have some fun, with the help of all of you.

I am posting an item to a friend of mine, specialised on fractional calculus, and I would like to prepare a nice packaging.

I have logarithmic paper, and would like the opening order something like a riddle, fractional calculus related, with some intriguing instructions.

Any help there? Regards. Image not related.
