That is because of priority in mathematical operations. First of all it gonna run 2**2 which is 2^2 = 4 So now equation is 4*2*2*1/2 Now it gonna simply multiply everything which is (16*1/2) And 16*1/2 is equal 8

It's because ** has more priority over * So, it is basically, >>> (2**2)*2*2*(1/2) = 4*2*2*0.5 = 8.0

There is a priority in python just like BODMAS in maths. The priority is 1.paranthese 2.exponents 3.multiplication and division 4.addition and subtraction Thats why exponent has been calculated first and then rest had been multiplied.

Exponents(**) is given more predecence than multiplication (*), so it will be like (2**2)*2*2*1/2 Which will be 16*(1 /2) equals 8
