function add(a, b) print(a + b) end money = add(5, 4) so I never called the function add(a,b) I only set it as a variable so why does it print to the output. Could this be used instead of using return because I can set a value to a function without return?

Money would be equal to nil, as you didn't return a value. However, it still runs the function, as you called it. Lua has the nice advantage of not throwing exceptions in situations like this, as opposed to languages such as Java.

You called the function, and inside the function it says to print it to the output. function add(a, b) return (a + b) end choo choo
