The important point, though, is that there are appropriate mathematical approaches that don't make any more errors than verbal logic. Sometimes it's easier to catch a mathematical error, because there are such well-defined rules about what can be done with the notation.

That was the point, the methods aggregate where aggregation erases the differences that are important. 
Yes, verbal logic makes some of the same mistakes but are more readily found.

Mathematics does not aggregate. Some mathematical methods aggregate.

The other points are all about omitting key elements from their analysis, which can just as easily be done with verbal logic.
