import math# Correct function - additiondef add(x, y):   return x + y# Correct function - subtractiondef subtract(x, y):   return x - y# Incorrect function - multiplication with incorrect operator precedencedef multiply(x, y):   return x * y + 2# Correct function - divisiondef divide(x, y):   if y == 0:      return "Cannot divide by zero"   else:      return x / y# Incorrect function - square root with incorrect factordef square_root(x):   return math.sqrt(x) * 2# Testing the functionsprint("2 + 3 =", add(2, 3))print("5 - 2 =", subtract(5, 2))print("4 * 3 =", multiply(4, 3))print("6 / 3 =", divide(6, 3))print("Square root of 16 =", square_root(16))

2 + 3 = 55 - 2 = 34 * 3 = 146 / 3 = 2.0Square root of 16 = 8.0
