Our reading
An editorial interpretation.
The list turns the sound of arithmetic terminology into comic nonsense. Words associated with striving, distraction, ugliness, and ridicule appear where mathematical categories would be expected. The humour depends on that almost-familiar language, making an orderly subject seem suddenly unruly and strange.
