The first part asks, If not 1+1=y, means 1+1 doesn't equal y, which is False because y is 2. So 1+1 is 2. Then the second part asks if x==4, this is True because x is 4. Since it is an "or" statement between the two equations( not 1+1=y or x==4), only one has to be True in an or statement, thus gets a True. True or True = True True or False = True False or True = True False or False = False The final equation asks if 7==8(or 7>8), which it isn't so it's False. Since the first set of equations eventually come out as True but the last one comes out as False, the entire line is False. You learn earlier that for a statement with "and", the entire equation has to be True. The final equation( 7>8 whichever showed up for you 7==8 ) makes the whole thing False. True and True = True True and False = False False and True = False *corrected False and False = False That makes the first print command invalid so it goes to the elif, which asks whether x > y, which it True, so "No" is printed.

Yes. Sorry, you're right. Was typing fast and made a lot of edits so ended up being a little sloppy.
