A root of confusion in math is not knowing whether a term is a noun, verb, adjective, or adverb.
An equation is nothing but a string of nouns. But I may think about these nouns, by their adjective or adverb alternatives, for example, which convolute the matter.
Verbs in math are really the outliers. Thus, I've been thinking wrong with "math is a verb" mentality. The most common math terms are nouns, which function alone as subjects and objects.
What I think of as "doing math" is akin to "doing porch". It entails a deck, railing, stairs, a chair, a roof. So too, does math include these things.
I walk on the stairs and deck. I sit on the chair. I enjoy the roof's shade. So too, the things of math are used via terms which are not included usually in math terminology.
Almost the only verb used in math is "think" which is convoluted by the subjects/objects which I employ during thinking.
