why do i get a error in this code

Question

def add_numbers(x, y):
total = x + y
return total

x = 5
y = 4
z = add_numbers(add_numbers(x,y),(add_numbers(x,y))

print(z)

Answer 1

line 7, where you are calling the function add_numbers(), you have too many brackets in the 2nd argument. Here's the corrected version:

z = add_numbers(add_numbers(x,y), add_numbers(x,y))

Answer 2

Wow OK thank you the simple things screw me up you have to pay close attention in coding
