Math notation is just terrible in general because a lot of it is shorthand made up by someone who likes single-letter variables. A symbol you can't type, something above, something below.
A for loop is clear and descriptive.
Or if you're feeling fancy, you could go functional with
reduce(add, range(0, 5), 0).Mathematical notation was designed to be written by hand. It is at least as clear and descriptive as any syntax from a programming language. You're pretending that the abstraction behind a for loop is somehow less than that behind a sum or product notation.
