# [ ] Fill out the function is_even with a code block that returns True if n is even and returns False if n is odd def is_even(n): #TODO if (x%2)==0: return True else: return False # Test the function x = 5 if is_even(x): print("Number is even") else: print("Number is odd")

5 + 2 * 8

(5 + 2) * 8

12 / 4 * 3

# Method 1 12 / (4 * 3)

# Method 2 12 / 4 / 3

# [ ] Correct the following expression so the answer is 10 (4 + 16) / 2

# [ ] Correct the following expression so the answer is 250; review the operator precedence table and use only one () pair 2 * (3 + 2) ** 3
