 Mar 29 comment RegionIntersection: Point or Line? Technically, I suppose, a line with no length may be equivalent to a point. However, I would expect Mathematica to return it in its standard form. In the particular case I am working on, I am trying to count the number of times a line crosses another line. Of course there is a workaround, but it is a bit clumsy.

Yes, I've used RegionIntersection in many other cases in which it returns a combination of Points and Lines Mar 28 revised RegionIntersection: Point or Line? added 25 characters in body Mar 28 revised RegionIntersection: Point or Line? added 61 characters in body Mar 28 asked RegionIntersection: Point or Line?

But I am using version 10. What version are you using? Jan 20 awarded Yearling Jan 18 comment Oddity with ToExpression Jason B, It still seems to be a bug. Jan 18 asked Oddity with ToExpression Dec 29 awarded Nice Answer Dec 11 comment How can I define operators that have the behavior I want? Doesn't Mathematica automatically simplify logic expressions? In this case Union[Intersection[a,b],b] should be automatically be simplified to b if a, b are sets. By the way, = is the assignment operator, Set; Equal is ==.

Oct 4 comment Converting imported data into a list of pairs +1 Nothing fancy. Nice and clean.

I wasn't aware that Simplify could make boolean inferences.
