00:00:00,000 --> 00:00:00,033


2
00:00:00,033 --> 00:00:02,433
This week, again, so a 
long table of contents.

3
00:00:02,433 --> 00:00:04,433
The idea is that every bullet 
should cover one minute,

4
00:00:04,433 --> 00:00:08,066
so if you'd like to look at a specific 
topic go to that minute mark

5
00:00:08,066 --> 00:00:10,233
and hopefully 
it's there.

6
00:00:10,233 --> 00:00:13,066
Clearly we'll be off by a minute 
since we start at zero minutes.

7
00:00:13,066 --> 00:00:16,733
We'll talk about divisibility theorems,
converses, “if and only if”’s.

8
00:00:16,733 --> 00:00:20,433
We spent a lecture talking about 
sets, those are pretty important,

9
00:00:20,433 --> 00:00:23,533
and they’ll be used throughout 
your mathematical career.

10
00:00:23,533 --> 00:00:28,433
Quantified statements, again, another 
core concept of mathematics, in general.

11
00:00:28,433 --> 00:00:30,633
So we'll talk about “for 
all” and “there exists”.

12
00:00:30,633 --> 00:00:33,166
We'll talk about assuming “for
all” statements, we'll talk about

13
00:00:33,166 --> 00:00:35,900
domain and how it's 
important for problems,

14
00:00:35,900 --> 00:00:38,733
and then we'll talk about approach 
to quantified statement problems,

15
00:00:38,733 --> 00:00:40,933
if you're trying to prove or disprove 
them, how do you do that?

16
00:00:40,933 --> 00:00:44,700
Then we'll talk about negating and 
nesting quantifiers to finish up the week.

17
00:00:44,700 --> 00:00:44,866
Then we'll talk about negating and 
nesting quantifiers to finish up the week.
