All right.
So now we're talking about less than we just talked about.
Greater than and greater than or equal to.
So this one should be much shorter.
In fact, the total time that it will take will be less than the previous video.
Yeah.
So it works the same way, although it does the opposite.
If you're familiar again, it's just the less than bracket.
The angle bracket I think is what they're called.
Just remember that.
So shift.
And then on most keywords, it's a comma.
So we can do things like this.
So rather than selecting all books released after 2000, we just switch it to the less than sign and
I'll select star from books where released.
Here is anything below the number 2000.
So if we try that select title and release here from books, if we do all of them and let's do our order
by again release tier just to make it easier to see where we have missing gaps.
Okay, so we want all of these to disappear.
Or excuse me, we want all of these to disappear.
And we only want to select these five.
All we need to do is add in our where.
Released here is less than 2000.
And there we go.
So that's pretty much all I'll say about it for now.
Along with that, of course, we have less than or equal to which works the same way that greater than.
Well, it doesn't work the same way it works in the same way that greater than or equal to does.
So if I wanted to include the year 2000 for whatever reason, I just need that equal sign after the
less than sine.
And now we get the same five books plus the one that was written in 2000.
Amazing Adventures of Kavalier and Clay.
That's pretty much it.
I will throw up a few exercises here if you want to try evaluating them, and then we're moving on to
some more interesting and complex operators.
All right.
So I'm back here.
I typed up a couple of quick exercises.
Go ahead, try this out.
I'll throw up that same graphic again and I'll be back in 1/2.
Okay.
I'm back here.
So let's go through these quickly.
The first one is three less than negative ten.
Well, I don't think so.
But let's verify.
You can see zero.
Meaning false.
It's not.
Is negative ten, less than negative nine.
Yes, it is.
It's lower than negative.
Nine is 42 less than or equal to 42.
Hope need to add a space there.
And as you would expect, we get yes, we get one.
True, because 42 is equal to 42.
And now on to the odd string ones.
It's the letter H lowercase less than the letter P, also lowercase.
And if you remember to the last video how this works, h comes before P and they're both lowercase.
So yes, this should be true and it is.
Okay, so this final one is uppercase.
Q Less than or equal to lowercase?
Q Well, this should be review from the last video because remember, that case doesn't matter.
So we see that, yes, indeed it is true.
Uppercase Q is less than or equal to lowercase Q and if we get rid of the equal to.
This is basically a duplicate of what we just did in the last video.
But I just want to hit this home that it is not lower.
It's not greater than they are equivalent.
Well, that's a minus sign.
There we go.
They're equivalent.
As you can see, we get true or one.
Okay.
Next up, moving on to much more exciting, much bigger and important logical operators.
