The best thing would be to have the shell have a syntax for arithmetic,
but then call out to bc to do the actual handling (because then you get
trigonometry and literally everything that bc knows how to do, with only
a minimal modification to the shell).
Syntactic sugar for a heredoc to bc itself.

And in the code attached to the original post, what's the outer "if" for?
No-one is ever going to call it with anything other than two args.
But I'm nitpicking. Maybe protection is better than readability.
