# 8 bagi 4 hasilnya 2 sisa 0 jadi jawabannya 0

# and Operator
True and True  # Evaluates to True
True and False  # Evaluates to False
False and False  # Evaluates to False

# or Operator
True or True  # Evaluates to True
True or False  # Evaluates to True
False or False  # Evaluates to False
1 < 2 or 3 < 1  # Evaluates to True
3 < 1 or 1 > 6  # Evaluates to False

# not Operator
not True  # Evaluates to False
not False  # Evaluates to True
