    Bignum=Integer Fixnum=Integer

    def sum_terms(n) (1..n).reduce(0) {|sum,n| sum + n**2 +1} end

    #NEVER DO THIS
class Object
	Bignum=Integer
	Fixnum=Integer
end

def sum_terms(n)
	1.upto(n).inject(0) {|sum, n| sum + n**2 + 1}
end

    what a terrible challenge. This is the most complicated way of doing n**2 + 1 given that the input is n=25

    Fixnum = Integer
Bignum = Integer

def sum_terms(n)
    1.upto(n).inject(0) {|sum, n| sum + n**2 + 1} 
end

    No matter what I try, including the posted solutions, I get some error related to Fixnum and Bignum. The proposed fix for this error doesn't work, either.
