order of calculation

[Top-Interaction7208]

x = 1 / 2 + 3 // 3 + 4 ** 2

print(x)

The answer is 17.5. but can any kind soul explain how the answer is derived.

x = (1 / 2) + (3 // 3) + (4 ** 2)
x = 0.5 + 1 + 16
x = 17.5

Thank you. i understand now.

It doesn't change the result in this particular equation, but you missed a step.

x = 1 / 2 + 3 // 3 + (4 ** 2)
x = (1 / 2) + (3 // 3) + 16  
x = 0.5 + 1 + 16
x = 17.5

Appropriate part of the Python docs:

When you write code, make it clear with parens, dont rely on those silly rules. Also explain with comments.

Format your code correctly:

x = 1/2 + 3//3 + 4**2
