I want to make a poster:
(a,b) is a point, unless it& #39;s an interval.
^-1 means reciprocal, unless it means inverse.
Order of operations is PEMDAS, but don’t take it literally.
Nothing, a dot and x all mean the same thing, unless the nothing isn& #39;t anythingl
What else??? #MTBoS

You can& #39;t take the square root of a negative, until you can.
0/anything is 0. anything/0 is undefined. Yet 0/0 can be literally anything.
