While Loop Sum

I'm trying to write a program to sum numbers, without using an array, and it's not working right. It's only giving me an output of 100.

n = 0
sum = 0
while n <= 99
    n += 1
    sum = n
end

puts sum

Hey! Try it with sum +=....

n = 0
sum = 0
while n <= 99 
  sum += n
  n += 1

end
puts sum

Really close to what you had already! That what you were looking for?

Yes, incrementing sum fixed the problem. I don't know what my problem is. As I'm learning, it seems like the simple things are tripping me up. Thank you.
