Everything else looks good to me.  But,

What's "greater" when you have two dimensions?

Since we can model the terminal display as an inner product space,
the terminal driver can compute an orthographic projection of the
plane onto a line and from there use routine arithmetic inequality
operators.

In any case, this is going to be confusing.  Can we get some wording
that is obvious to a school student?


Have a lovely night!

The problem with the Linux kernel's terminal driver's lack of developer
attention over the years is obviously a result of it presenting
insufficient features of interest to the linear algebraist.
