comment Why do some mathematical ideas seem counter-intuitive?
@AsafKaragila I is an engineer; pretty sure ignoring the actual question and nitpicking the small mistakes is right there in my job description

comment Euler's totient function
This was mentioned in one or more answers, but just to restate as a comment: the totient function is not always the product of one less than the prime factors; if a number has n multiples of the same prime factor, you use p^n - p^(n-1); in the case where n==1, you would use p - p^0 which is p - 1.

comment Father and daughter river crossing puzzle.
Another variant (Italian I think) relaxes constraint 3 to allow the case where the man won't ravish someone's sister if his sister is also present as a chaperone)
