Well, there is no variable "result" and you've aliased the builtin function 'sum()' and how would you expect that sum() would have known you wanted 'r' as it's input when you gave it a vector of two integers???
Start w/ the "Getting Started" section tutorial and work your way through some beginning steps...
For the question you've asked,
r=rand(53,1); % don't need the [] to make inputs a vector s=sum(r); % sum up the values you got... disp(s) % or forget trailing ";" & ML will echo automagically
