I don't regard most of my opinions very highly. -- Aatu Koskensilta (aatu.koskensilta(a)uta.fi) "Wovon man nicht sprechan kann, dar�ber muss man schweigen" - Ludwig Wittgenstein, Tractatus Logico-Philosophicus

The solution to your situation is very simple: Ask your instructor for the answers to the questions, write them down and and turn them in. If you are correct in thinking that he would not mind you getting them from some else on the Internet, then what objection could he have to your getting them from him? Jim Burns

It depends upon a few things: 1. Whether you count zero or one as the first natural. 2. How you perform the exclusion of duplicate forms of the same rational (such as 2/1, 4/2, and so on). 3. Which way you zig-zag. Presumably, your homework has some explicit statement of these. If not, you'll just have to make some assumptions, state them, and count it out. >2.

That depends upon how you're doing the interleaving of digits.
