People have overfit on a formalized dialect of math, because we dont practice on anything else. If you beleive there are an infinite number of functions, youd probably also believe there to be an infinite number of notations for those functions. All math in the formalized language has come from randoms making up their own symbols and arrangement rules, often times for fun. (see Newton) Sometimes theres equivalent notations for the same concept. (see leibnitz). Just like you can say the same sentence in chinese, english, and spanish, you can express the same concept in different math. Even within the same language you can say the same thing ten different ways. Believing dogmatically in only one notation system would be silly. Put a modern calculus textbook, a 1920s boolean logic textbook, and principia next to eachother on the table. If you had only ever seen one before you'd think the others came from space. If Eric is making up math you would need to translate it to the dialect you understand. (Which would probably result in you understanding it, and then he might stick with the more colloquial translation.)
