00:00:01.370 --> 00:00:09.400
Use the place value counters to solve 3,243 take away 1,232.
00:00:11.110 --> 00:00:18.250
Hint: 3,243 has been shown in the place value table.
00:00:19.400 --> 00:00:21.040
What do you need to take away?
00:00:22.910 --> 00:00:36.180
In this question, we have to subtract 1,232 from 3,243, and we’ve been given a place value table to help.
00:00:37.030 --> 00:00:42.040
This shows the number 3,243.
00:00:42.900 --> 00:00:51.020
When we’re subtracting with large numbers, like these two four-digit numbers, we need to use the standard written method.
00:00:52.180 --> 00:00:55.890
We need to write each of the numbers in their correct place value.
00:00:56.790 --> 00:01:07.840
We can see from the place value table that 3,243 has three ones, and we need to subtract two because 1,232 has two ones.
00:01:08.690 --> 00:01:13.420
The tens digit in the number 3,243 is four.
00:01:14.070 --> 00:01:21.710
So we’ve got four 10s, and we need to subtract the three 10s in the number 1,232.
00:01:22.730 --> 00:01:30.700
There are two 100s in the number 3,243, and we need to subtract two.
00:01:32.300 --> 00:01:43.160
And 3,243 has three 1,000s, 1,232 has one, so we’re subtracting one 1,000 from our three 1,000s.
00:01:44.130 --> 00:01:51.390
When we use the standard written method or column subtraction, we always subtract the ones first.
00:01:52.050 --> 00:01:54.890
Let’s use our place value table and the counters to help.
00:01:55.860 --> 00:01:59.520
We’ve got three ones, and we need to subtract two.
00:02:00.750 --> 00:02:03.800
We know that three take away two is one.
00:02:04.840 --> 00:02:07.080
Now we can subtract in the tens place.
00:02:08.090 --> 00:02:17.020
We’ve got four 10s, and we need to take away three 10s: one, two, three.
00:02:18.320 --> 00:02:20.210
We’ve got one 10 left.
00:02:22.800 --> 00:02:29.410
On to the hundreds place, we’ve got two 100s, and we need to subtract two 100s.
00:02:29.920 --> 00:02:33.630
Here we go: one, two.
00:02:35.350 --> 00:02:37.150
We’ve got no 100s left.
00:02:38.330 --> 00:02:42.030
Finally, we move into the thousands place.
00:02:42.550 --> 00:02:46.580
We’ve got three 1,000s, and we need to subtract one of them.
00:02:48.080 --> 00:02:53.080
And we know that three take away one leaves us with two 1,000s.
00:02:54.210 --> 00:03:05.200
3,243 subtract 1,232 equals 2,011.
00:03:06.450 --> 00:03:14.100
We used column subtraction and our place value table and counters to help us subtract.
00:03:14.920 --> 00:03:23.480
First, we subtracted the ones, then the tens, the hundreds, and the thousands.
00:03:24.180 --> 00:03:31.880
3,243 take away 1,232 is 2,011.
