How do I stop making my own notations in math?
I know the axiom or structure of an equation/variable or a constant I want is most likely already formulated in another discipline but the closest tool is just looking up keywords in google and hope you find whatever you want

I feel like I will end up making my own language made up of the greek alphabet with some retarded symbol or sizes
