0:00:00.530,0:00:07.730
Determine whether 394 is greater[br]than or less than 397.

0:00:07.730,0:00:12.220
Then write the expression that[br]shows this using either this

0:00:12.220,0:00:15.020
symbol or that symbol,[br]and this is actually

0:00:15.020,0:00:16.570
the less than symbol.

0:00:16.570,0:00:19.480
We'll think a little bit more[br]about how to remember that.

0:00:19.480,0:00:22.000
That is the less than symbol[br]and this is the

0:00:22.000,0:00:25.690
greater than symbol.

0:00:25.690,0:00:27.270
So first of all, let's[br]just look at the two

0:00:27.270,0:00:30.290
numbers: 394 and 397.

0:00:30.290,0:00:32.009
So let me write them down.

0:00:32.009,0:00:45.820
394 and the other[br]number is 397.

0:00:45.820,0:00:48.480
Now, they both have 3 hundreds,[br]so their hundreds

0:00:48.480,0:00:49.650
place is equivalent.

0:00:49.650,0:00:53.880
They both have 90 with that 9[br]there, but this is 300 plus 90

0:00:53.880,0:00:59.200
plus 4 and this is 300[br]plus 90 plus 7.

0:00:59.200,0:01:02.025
And we know that 4[br]is less than 7.

0:01:02.025,0:01:04.830
If you look on a number line,[br]4 comes before 7.

0:01:04.830,0:01:07.850
If you're counting the 7, you're[br]going to pass up 4, so

0:01:07.850,0:01:12.610
394 is less than 397.

0:01:12.610,0:01:18.630
And the way that we write that,[br]we would just write 394

0:01:18.630,0:01:22.860
is less than 397.

0:01:22.860,0:01:30.740
And the way I remember that this[br]means less than is that

0:01:30.740,0:01:33.230
the smaller number is on the[br]side that has kind of a

0:01:33.230,0:01:34.070
smaller side.

0:01:34.070,0:01:36.870
You can imagine this side[br]is much smaller than

0:01:36.870,0:01:38.480
this side over here.

0:01:38.480,0:01:39.800
We could also write[br]it the other way.

0:01:39.800,0:01:46.050
We could write 397 is[br]greater than 394.

0:01:46.050,0:01:49.390
And once again, the bigger[br]number is the side that this

0:01:49.390,0:01:53.630
little thing is opening onto[br]or the side that has the

0:01:53.630,0:01:56.440
bigger side of this[br]symbol right here.

0:01:56.440,0:01:58.520
This point is the[br]smaller side.

0:01:58.520,0:02:00.060
This out here is the[br]bigger side.

0:02:00.060,0:02:01.380
That's where you put[br]the larger number.

0:02:01.380,0:02:04.050
Greater than, less than.
