Depends what you mean by “familiar”. I’d imagine anyone reading the essay can do algebra, but that they’re still likely to be more comfortable when presented with specific numbers. People are weird like that—we can learn general principles from examples more easily than from having the general principles explained to us explicitly.

Exceptions abound, obviously.
