00:00:01.570 --> 00:00:05.810
Arrange the expressions on these cards in descending order.

00:00:07.760 --> 00:00:12.530
We know that descending order means from greatest to least.

00:00:13.820 --> 00:00:18.330
So we need to choose which of these cards is greatest and work our way down.

00:00:20.180 --> 00:00:24.580
We notice that all of our cards are being multiplied by 10.

00:00:26.020 --> 00:00:33.470
And that means, we can look to the number that 10 is being multiplied by to determine the greatest.

00:00:35.040 --> 00:00:39.080
We have the numbers nine, six, eight, and three.

00:00:39.680 --> 00:00:43.090
And that will help us determine how to order these cards.

00:00:44.590 --> 00:00:48.570
Out of these four values, nine is the greatest.

00:00:49.670 --> 00:00:53.260
And that makes 10 times nine our largest value.

00:00:54.930 --> 00:00:58.580
After that, we have the digits six, eight, or three.

00:01:00.380 --> 00:01:02.830
Eight is the next largest value.

00:01:03.830 --> 00:01:07.560
Which means 10 times eight is the next largest card.

00:01:09.550 --> 00:01:12.540
After that, we have six or three.

00:01:14.210 --> 00:01:16.150
Six is larger than three.

00:01:17.360 --> 00:01:20.300
So 10 times six would be our next card.

00:01:22.000 --> 00:01:24.100
And we’re left with our last value.

00:01:25.320 --> 00:01:29.960
Our last card of 10 times three which would represent the smallest value.

00:01:32.010 --> 00:01:40.450
In descending order, we have 10 times nine, 10 times eight, 10 times six, and 10 times three.
