How many unique answers are there to all the natural whole numbers 1 - 99 multiplied by all the natural whole numbers 1-99? For instance all the single digits 1-9 multiplied by all the single digits 1-9 yields 32 unique answers between 1& 81. Do the graphs of these 2 problems show any fractal properties. What about 1-999 multiplied by 1-999
I calculate that there are, in fact, 36 unique products $ij$, with $1 \le i,j \le 9$.
For $1 \le i,j \le 99$, I find 2869 unique products.
For $1 \le i,j \le 999$, I find 247814 unique products.
I'll need to know more about what you mean by "graphs of these 2 problems" to say anything about fractals here.
