Using the loop construct, add the current value of number to the numbers array. Inside of the loop, add 1 to the number

What am i doing wrong?

loop.rb 
numbers = []

number = 0

# write your loop here
loop do 
  number =+ 1 
  number.push(numbers)
  if numbers == 3
    break
  end
end

 Bummer! NoMethodError: undefined method `push' for 0:Fixnum Did you mean? puts

Hi Philip,

You want to push onto the numbers array; pass in number as the method argument. Your error is saying that number doesn't have a push method - that's because it isn't an array; numbers is! :smile: 

numbers.push(number)

Also, you want to do that first in the loop, before you increment number otherwise your array will never have the value zero in it. The question wants add the current value of number to the numbers array - this includes the initial zero value. Next up; to increment, use += rather than =+.

That all looks like:

loop do 
  numbers.push(number)
  number += 1
  break if number == 3
end

Let me know how you get on.

Steve.
