Don't worry about the scary stuff. I'm just about clueless about mathematics, but doing alright as a web developer. The vast majority of programming jobs don't require any serious math. Lambda's are anonymous functions, by the way. They're not scary at all :) Here's one in Clojure: (fn [x] (* x 2)) It takes one parameter, called "x", and returns it multiplied by two. This function is not bound to any variable name, but just passed somewhere "on the fly".
