How this code is failing to give me an accurate answer?

this is my code which is working fine but it is not correct. I am unable to figure out the problem

class MathUtils:

    @staticmethod
    def average(a, b):
        return a + b / 2

print(MathUtils.average(2, 1))

>Solution :

you made a tiny mistake – what your code actually does is taking b, dividing it by 2 and then add the result to a. so you get 2 + 0.5 = 2.5

you need to put parentheses around a + b:

class MathUtils:

@staticmethod
def average(a, b):
    return (a + b) / 2

print(MathUtils.average(2, 1))
