i love that he started with simple ones and then worked up to the harder problems, he teaches so much nicer than my actual professor!

U r the best. but I think there is mistake, u said (A.B) = A or B and (A+B)= A and B but I guess it's the opposite (A.B)= A and B (A+B)=A or B right?

+Aboud Ramlawi correct. but turn on your annotations since he made some
@sikharoy16468 жыл бұрын
Exactly
@funmeister6 жыл бұрын
i was just going to comment the exact same thing. A.B is "and" while A+B is "or". my annotations is off, so didnt realize he corrected it there.
@reljoy6 жыл бұрын
How do you turn annotations on? I can turn on auto generated subtitles but annotations sound different.

6:19 should be AND. I know there's an annotation, but they're getting removed later in 2019. (and also are not visible on mobile)

The upside down carrot at 6:47 should be the opposite direction to be an "AND" statement I believe.. in that position that looks like a "V" is actually an "OR" statement i believe.... if i'm correcto!?

You're a great teacher. Very easy to follow.. You're structure of teaching this is excellent. My instructor made this hard when it's quite simple honestly... It just takes basic understanding of polynomials to simplify. Anyways he jumped into it in a weird way, but you nailed it. Just gotta say that appreciate you so much! I should of paid you instead of my college, but gotta have that slip of paper.

I would like to know whether we can use this strategy in solving such problems : Five travellers P,Q,R,S and T came from five different countries (Algeria,Belgium, Canada, Denmark and Egypt not necessarily in the same order) to visit the country of Pantina. They each flew on a different airline out of V,W,X,Y and Z (not necessarily in the same order). As all the five travellers were staying at the same hotel they met up at the hotel café and were discussing which country they were from and which airline they had flown in on. At the end of their discussion the following information was available. • T is not from Canada • Q is not from Egypt • The airline that the traveller from Canada flew on was not X • The airline that the traveller from Algeria flew on was neither V nor Z • Travellers P and Q both are not from Canada or Denmark • Travellers P and Q both did not fly on either airline W or X • S is not from either Algeria or Egypt • The traveller who flew on airline W is neither from Denmark nor Canada • Neither R nor T flew on airline V or W and neither of them is from Belgium or Egypt???
