Hi ruby-foum!

I’m trying to find the sum of all of the integers within a given range, up to and including the base and highest integer:

def get_sum(a,b)

@a = a

@b = b

if @a == @b

return @a

else

return (@a…@b).to_a.sum

end

end

*this works fine on positive integers. however,*

get_sum(0,-1)

*returns 0. I would expect -1?*
