I am reading CTM by Van Roy/Haridi and watching Van Roy's edx vids. Very nice explanations that require a lot of filling in the holes.

If someone else is familiar with Oz/Van Roy stuff, I have a question.

I am, but I read it many years ago, so I might not be able to help

In this video[0] Van Roy claims that the function Three "resolves" to 3. It's at around 8:45 minute. I tried working that out, but can't seem to get it correct. What I tried

   {Inc {Inc {Inc Zero}}}
   {Inc {Inc 1}}
   {Inc {1} + 1}
   {{{1} + 1} + 1}

Can we consider {{{1} + 1} + 1} to be 3 or what are my mistakes? Thanks.
