This is a valid question. Others have provided a much better answer, the thing I want to add is that being able to express computation in software the same way as in research papers makes the code much easier to read and reason about. This language was invented a long time ago to express computations concisely, and today you will see a lot of math built on top of these abstractions (since they’ve been around for sooo long).

So the ability to express computation in standard mathematical notation rather than having to invent pseudo symbols to do it makes it much easier to read for people who already have that training. And for people who don’t… it does require pre-reading to understand how these symbols are used but you have the benefit for hundreds of years of math literature and community to look it up!
