Turns out you can create PDF files with the Xerography device down the hall. Here at long last are 67 pages of Numbers, Sets, and Logic by yours truly. You couldn’t really print it all out and use it with your own classes—yet; it’s got scribblings by me from classroom use on some early pages and breaks off in the middle. For that matter, the drawings are exactly as ugly as my blackboard work. But I’ve wanted to put some version of this up on the web for years (without having to reformat everything by hand) and am thrilled to have suddenly broken through to here. I posted re-formatted versions of section 1.1 and 1.2 in this very blog back in July.
