not 1 + 1 == y or x == 4 and 7 == 8 Let's change the variable names to their values to increase readability: not 1 + 1 == 2 or 4 == 4 and 7 == 8 Arithmetic operators are performed first: 1 + 1 = 2 not 2 == 2 or 4 == 4 and 7 == 8 Comparison operators are performed second: 2 == 2 = True 4 == 4 = True 7 == 8 = False not True or True and False Now there are only logical operators left. Comparison operators also have an operator precedence: not: first, and: second, or: third. First let's get not True: not True = False False or True and False Then let's get True and False: True and False = False False or False Then let's get False or False and we'll have the final result: False or False = False final result: False
