Ok, good point. So what are you trying to say? That the general public should use the more specific word for the benefit of mathematicians?

Except that arithmetic still qualifies as maths even if it is only barely, whereas a golf cart doesn’t qualify as a sports car. It’s more like saying “vehicle” when you mean "kid’s bicycle "; it’s still technically true even though it isn’t the most sophisticated.

For the general public that’s a distinction without a difference

Ever heard of cash?

Service vs leadership is a false dichotomy. You can (and should) be a leader who serves. Mamdani is serving NYers in a leadership position. He makes the calls and has the responsibility for decisions that serve his constituents.

The fact that you call kilometers “klicks” does my head in since the rest of the English speaking world shortens it to “kays”
