Using “suru” to turn a noun into a verb isn’t that different from how we use “to do” in English. For example, you would never say “That man can math”, you would say “That man can do math”.
The big difference here is that “to do” comes before the noun but “suru” and “shimasu” comes after.
する = to do
来る = くる = to come
勉強 = べんきょう = study (noun)
勉強する = to study (verb)
