Array trouble

[Clayton]

i have a function called add, and from wtd's tutorial, it should be able to take any number of integers and form them into an array, however, it doesnt seem to be working right. my code:

Ruby:

def add(*integers)         total = 0         integers.each do |array_element|                 total += integers(array_element)         end         return total end puts "#{add(1,2,3,4,5,6,7,8,9)}"

I keep getting an error on line 3 and I don't know why (I think it has something to do with "integers" but i dont know for sure.)

In your function, "integers" is an Array.

When you use "each" it passes each element of the Array to the block in turn.

code:

def sum(*integers)    total = 0    integers.each { |integer| total += integer }    total end

But then, you really should...

code:

class Array    def sum       inject(0) { |a, b| a + b }    end end

code:

[1, 2, 3, 4].sum # => 10
