"In Lean, types are terms, too, and so they have types, as we have already seen. So what is the type of 1 = 1. It’s Prop."

I believe a question mark would work better for the "So what is the type of 1=1" sentence, like so: "In Lean, types are terms, too, and so they have types, as we have already seen. So what is the type of 1 = 1? It’s Prop."

"We we have the following picture of the type hierarchy for the terms we’ve just constructed." One of the "we" should be deleted.
