Thanks Richard, I'm not sure why you weren't able to leave a comment on the blog as I have received comments on this post recently. In any case, I am not sure what you mean by introducing the visual of _ ? Are you thinking that the 2-3 example should be shown before the - 1 2 3 4 5 rotation animation, or maybe something different again.
I think your examples of the _1 + _1 and -1+-1 could be included in a lab specifically focused on number representation, but I was working with 'An Idiosyncratic Introduction to J' as the base content and I felt that I didn't want to venture too far into that realm. Thanks again for your feedback. Cheers, bob On 2011-04-25, at 12:39 AM, Richard Hill wrote: > Just looked at it. Its good. > Tried to leave a comment there.
