Go and continue to wallow on your ignorance. If you could not follow the example at the link which I had copied in post #429, you are beyond help. And to claim you are more lnowledgable than an award-winning math teacher is just plain stupid.
I heard you the first time. You cite one website, and even he admits that his juxtaposition theory is not final and that most software doesn’t follow his theory.
And the idea that teachers are infallible is laughable. I’m worried that she is really teaching kids that 9 / 3 * 3 is 1.
