This is called "prefix notation". The operator comes before the operands and every expression goes in parentheses.

For instance you could write:

(+ 1 2 3 4)

Which would evaluate to 10.

This syntax is from a family of programming languages usually called LISP.

Awesome thanks for explaining that. That's cool as hell.

I understand prefix notation, but you got the order of operations wrong...
