+ 1

Please, help me understand this: print(not(2==3 or 2==3 and 2==3)) ==>True print(not(2==2 or 2==2 and 2==3)) ==>False should I operate 'and ' before 'or'? or simply operate from left to right? it's spinning my head please!

Confused on Precedence Operation.

Step1=(2==3 and 2==3) =(false and false)=false Step2=(2==3 or false)=(false or false) =false Step3=(not false)=true Step1= (2==2 and 2==3) =(true and false)=false Step2=(2==2 or false)=(true or false) =true Step3=(not true)=false

" And" is performed before "or" the same way multiplication is performed before addition unless brackets specify otherwise. Think of it as math.
