Let ##T = \{ \frac{n}{m}\in \mathbb{Q} \vert n, m \in \{ 1, 2, ..., 9 \} \}##
No values can repeat (e.g. ##\frac{2}{2},\frac{3}{3},...##)
How many elements does the set have. I could just go ahead and count the elements and eliminate the repeats, but I'm wondering if there is a simpler (and more elegant) way to do it?
Thanks
