Mathematics is a fine subject of Study, but it requires supervised effort, which We Rhinos cannot dedicate to it. We are numerically ignorant, and often have important things to do.
Sometimes a Mathelete will appear on the scene, flexing Mathematic Muscle. We honor those who understand the subject, but wonder why they bother. Juggling big numbers has not been shown to improve matters, at least to Rhino Satisfaction.
We Rhinos are content that We maintain our State of Mind by limiting how much We burden it with whatever comes after three. “Lots” covers that topic, and has for zillions of years, or close to it. Would counting to bazillion change our lifestyle? We hope We never know.
