Can someone explain LISP to me basically?

[50]

Hello, I missd half of my comp sci A class on friday and the teacher taught lisp in the half I missed. I asked him and he said look online but I couldn't find a site that explains what I am trying to do. The practice test problem is

Evaluate:

(MULT (ADD 2 3) (SUB 4 6))

This looks really easy but I have no idea how to do lisp. Can someone basically explain how to do this problem? Thanks

I don't know LISP but that problem was pretty much self-explanatory...

Is this for a college or high school course? When I add Comp Sci A in high school, the class only taught Java, and the exam only covered Java.

Lisp:

(operator operand operand)

So (add 2 3) = 2+3
