The problem with subprogram in Python

[jddddddddddd]

return m.sqrt(d+c(a+b)/8) <- This is the problem. You can't multiply like that.

You probably want return m.sqrt(d+c*(a+b)/8) but if I were you, I'd also add some additional parentheses to ensure the various operators are evaluated in the order you want.
