Mistake
- Problem $29$ of the Rhind papyrus is not quite so clear, but it is plausibly the first ever 'Think of a Number' problem. It reads ...
Correction
According to 1923: T. Eric Peet: The Rhind Mathematical Papyrus, which David Wells cites, this is actually Problem $28$.
It also needs to be pointed out that there are a number of such problems of a similar nature in this section of the Rhind Papyrus, so this particular instance cannot really be considered to be "the first ever".
