>>11714668OP has 3 gay male lovers who painted their buttholes blue
OP plugs 1/3rd of the holes with a red dildo
OP plugs another 1/3rd of the holes with another red dildo
now 2/3rds of the holes will be plugged with dildos leaving another one empty for him
But more specifically the top is wrong because of the subscripts, 1/3+1/3 doesn't fucking equal 2/6. Without the subscripts it's ambiguous so both are right depending if you interpret the left side as two fractions or two groups
