You probably also don't use a calculator because it uses a scary language called arabic numerals. Why write 123,456 when you could write out in english: One Hundred Twenty-Three Thousand Four Hundred Fifty-Six? English is your programming language and also your math language, right?

I hope this comment is sarcastic.

LLMs are able to ingest numbers. And not just Arabic numerals; Did you know that there are other kinds of number systems?

Believe it or not, they also ingest multimedia. You don't need the English language to talk to a language model. Anything can be a language; you can communicate using only images.

And for that matter, modern LLMs are great at abstract math (and like anything else the results still need proofreading).
