00:00:01.030 --> 00:00:10.890
Find the number added to 7334859 to give eight million.
00:00:12.670 --> 00:00:20.630
Let’s imagine this blue space represents 7334859.
00:00:22.040 --> 00:00:24.930
The yellow space is eight million.
00:00:26.970 --> 00:00:38.780
The green space would be equal to the number we need to add to 7334859 to give us eight million.
00:00:40.760 --> 00:00:48.660
To find the missing space, we need to take the blue space away from eight million.
00:00:49.650 --> 00:00:58.390
We need to subtract 7334859 from eight million.
00:00:59.590 --> 00:01:03.870
Eight million is an eight with six zeros behind it.
00:01:04.880 --> 00:01:09.160
We line up our units carefully and then we can subtract.
00:01:10.980 --> 00:01:16.430
When we look at our units place, we’re trying to take nine from zero.
00:01:17.080 --> 00:01:18.540
And that’s not going to work.
00:01:19.360 --> 00:01:20.510
We need to borrow.
00:01:21.370 --> 00:01:31.500
We can’t borrow from the tens place or the hundreds place or the thousands place or the ten thousands place or the hundred thousands place.
00:01:32.060 --> 00:01:34.660
We have to borrow from the millions.
00:01:35.450 --> 00:01:42.230
So we take one away from our millions and then we have ten hundred thousands.
00:01:43.350 --> 00:01:46.820
We take one away from our hundred thousands.
00:01:47.160 --> 00:01:52.950
That gives us nine hundred thousands plus ten, ten thousands.
00:01:53.920 --> 00:02:03.120
If we take one away from our ten thousands, we will be left with nine ten thousands and ten one thousands.
00:02:03.740 --> 00:02:08.250
Following that same process, we take one away from our thousands.
00:02:08.610 --> 00:02:13.350
That leaves us with nine thousands and ten hundreds.
00:02:14.440 --> 00:02:18.270
We do the same thing, take one away from our hundreds.
00:02:18.540 --> 00:02:22.960
That gives us nine hundreds and ten tens.
00:02:23.900 --> 00:02:32.980
And finally, we’ll take one away from our tens leaving us with nine tens and ten ones.
00:02:33.960 --> 00:02:35.840
And now we can subtract.
00:02:37.070 --> 00:02:42.130
In the units place, it now says 10 minus nine which equals one.
00:02:43.440 --> 00:02:48.170
In the tens place, nine minus five equals four.
00:02:49.390 --> 00:02:54.040
In the hundreds place, nine minus eight equals one.
00:02:55.100 --> 00:02:59.690
In the thousands place, nine minus four equals five.
00:03:00.560 --> 00:03:05.130
In the ten thousands place, nine minus three equals six.
00:03:06.140 --> 00:03:11.440
Also in the hundred thousands place, nine minus three equals six.
00:03:12.260 --> 00:03:17.210
In the millions place, we have seven minus seven, which equals zero.
00:03:18.460 --> 00:03:30.980
When we take 7334859 away from eight million, we get 665141.
00:03:32.760 --> 00:03:40.780
That is what you would add to 7334859 to give you eight million.
