@@mxlexrd yes I did. That’s what comes of trying to do the negation in your head. Anyway, it makes sense because P and not Q represents a counter example.
Let's say P is false and Q is false. So, ~Q-->~P is true, which means P-->Q is also true. But, Q is false, so P-->~Q is true. So, P-->Q and P-->~Q, but we don't have any contradiction.
this guy has been helping me with math since middle school. now i'm a CS student and he's still carrying me through it. my hero
me too

Technically speaking, if P is false, both P -> Q and also P -> ¬Q. So P -> Q and P -> ¬Q aren't strict logical negations.
Yep. They’ve been making this mistake throughout the series. The real negation of P -> Q is not P and Q
@@jeremypnet I think you mean P and not Q.

Do you add to e at the top of your whiteboard each lesson?
That's not e. e's decimal expansion starts with 2.7....
That's log base 2 of 5
It's used in another video that was filmed in the same class, right after this video
AWESOME

what class
i mean wich grade
Year 12 extension 2 mathematics which is the hardest maths you can do in Australia
12/02/2021 + Madam I'm Adam = 22?
I think the implication is that the date is a palindrome. 12/2/21.
