00:00:01.670 --> 00:00:03.380
Fill in the missing number.
00:00:05.890 --> 00:00:12.430
Here we see an example of someone multiplying 184 by 76.
00:00:14.960 --> 00:00:20.220
This is an example of multiplying a three-digit number by a two-digit number.
00:00:22.150 --> 00:00:31.560
And when we multiply something by a two-digit number, this spot is filled in by what we call a placeholder.
00:00:31.810 --> 00:00:34.420
We have to hold this space open.
00:00:34.480 --> 00:00:36.170
It is empty.
00:00:36.700 --> 00:00:41.810
What number do we usually use to represent empty or a placeholder?
00:00:43.950 --> 00:00:44.630
Zero.
00:00:44.870 --> 00:00:48.130
The missing number from this position is a zero.
00:00:50.230 --> 00:00:55.440
Now that we know what goes in this position, we can complete the calculation.
00:00:55.880 --> 00:00:56.680
We can add.
00:00:59.330 --> 00:01:07.350
To complete the calculation, we’ll add 1104 to 12880.
00:01:08.840 --> 00:01:13.530
Starting all the way on the right, four plus zero is four.
00:01:14.900 --> 00:01:17.360
Eight plus zero is eight.
00:01:18.460 --> 00:01:20.730
One plus eight is nine.
00:01:21.020 --> 00:01:23.210
One plus two is three.
00:01:23.570 --> 00:01:25.720
One plus zero is one.
00:01:28.380 --> 00:01:33.630
The completed calculation is 13984.
