Question 1

[Razi Asaduddin]

do we have to do question 1a like :
leftAssocSub = do n <- num; nums n

Then what is nums? a normal function ? what is the type of nums?
i dont understand how to implement it that way..


Why cant i just add everything after the first number together and subtract
that result from the first number?



thanks

I read the question as saying that it "can" be implemented with a nums
function as it describes. not that it "has to be". I did it your way.
Just be sure you handle a case with double negative signs like 5--2-1 = 6
