Okay, so they tell us to assume that a, b, and c are equal to 5, 6, and 8 respectively.
00:11
Okay.
00:12
So then which of the following statements are false? a ask is a equal to 5? well, that's true.
00:21
They're asking which ones are false.
00:22
Well, unfortunately, a is not false, so we can disregard that one.
00:25
Let's see, b, 7, less than are equal to a plus 2.
00:32
Well, in parentheses, so let's see, a plus 2 is 5 plus 2, which is 7.
00:40
So is 7 less than are equal to 7? yes, it's equal to 7.
00:44
So that's also true.
00:46
Not what we're looking for.
00:47
We're only looking for false statements.
00:49
Then we have for c, let's see.
00:52
Is c less than are equal to 4? well, that's 8.
00:56
Is 8 than are less than are equal to 4? no, it's greater than.
01:00
Strictly greater than.
01:01
So this is false.
01:02
This is one of the ones we're looking for.
01:05
Let's see.
01:07
For d, they ask is 1 plus a.
01:12
Remember a is 5...
