He heard it from me, also, and I think others at XOCamp2. The infix
tiles were incomplete without some form of parentheses.

With these arithmetic tiles and square root, I can do all of Euclidean
synthetic plane geometry and all of plane analytic geometry up to
quadratics, plus a wide range of Computer Science topics, and physics
and biology simulations. With user-defined tiles that can call any
Python function, I can do special functions, calculus, complex
numbers, and differential equations. That means that we can experiment
to see how much of the ideas behind these subjects we can introduce in
the early grades, so that children will be far more ready for the full
subjects when they get to them.

My next request is a While loop.
