0:00:00.600,0:00:08.880
We need to add 7.056[br]to 605.7 to 5.67.

0:00:08.880,0:00:11.170
Now when you're adding any[br]number, you always want to

0:00:11.170,0:00:14.370
make sure you line up numbers[br]in the same place.

0:00:14.370,0:00:15.910
And especially when you're[br]dealing with decimals, the

0:00:15.910,0:00:18.790
easiest way to do that is to[br]just line up the decimals.

0:00:18.790,0:00:19.783
So let's do that.

0:00:19.783,0:00:27.010
So the first number right[br]here is 7,056.

0:00:27.010,0:00:36.700
This second number right[br]here is 605.7.

0:00:36.700,0:00:43.150
And then this last[br]number is 5.67.

0:00:43.150,0:00:44.940
So now we have everything[br]lined up.

0:00:44.940,0:00:47.340
Everything that's in the ones[br]place is below or above

0:00:47.340,0:00:49.420
everything else in[br]the ones place.

0:00:49.420,0:00:52.430
Everything in the tenths place[br]is below or above everything

0:00:52.430,0:00:55.190
else in the tenths place,[br]and so on and so forth.

0:00:55.190,0:00:56.770
So we can add.

0:00:56.770,0:00:58.020
So let's add it.

0:01:01.370,0:01:03.690
So you want to start off[br]in the smallest place.

0:01:03.690,0:01:05.040
So you start off here.

0:01:05.040,0:01:08.950
This is the tenths, hundredths,[br]thousandths place.

0:01:08.950,0:01:11.680
This is literally 6 thousandths,[br]and you want to

0:01:11.680,0:01:13.170
add it to the other[br]thousandths.

0:01:13.170,0:01:14.990
There aren't any other[br]thousandths.

0:01:14.990,0:01:15.950
So you can view it two ways.

0:01:15.950,0:01:19.770
You can just bring in this 6[br]down, or you could view this

0:01:19.770,0:01:26.450
605.7 as the same thing[br]as 605.700.

0:01:26.450,0:01:29.920
You can add as many zeroes to[br]the right of this decimal, to

0:01:29.920,0:01:31.970
the right of the 7, as you want,[br]since we're sitting on

0:01:31.970,0:01:34.890
the right side of the decimal,[br]without changing its value.

0:01:34.890,0:01:35.840
You can also do it here.

0:01:35.840,0:01:41.350
This 5.67, you can write[br]it as 5.670.

0:01:41.350,0:01:42.800
When you write it like[br]this, and you have 6

0:01:42.800,0:01:44.910
plus 0 plus 0 is 6.

0:01:44.910,0:01:45.780
And you keep going.

0:01:45.780,0:01:51.550
5 plus 0 plus 7 is 12.

0:01:51.550,0:01:54.480
You write the 2 in the[br]hundredths place,

0:01:54.480,0:01:56.130
and carry the 1.

0:01:56.130,0:02:02.440
1 plus 0 plus 7 is[br]8, plus 6 is 14.

0:02:02.440,0:02:06.170
Write the 4, regroup the[br]1 into the ones place.

0:02:06.170,0:02:07.950
1 plus 7 is 8.

0:02:07.950,0:02:09.759
8 plus 5 is 13.

0:02:09.759,0:02:13.350
13 plus 5 is 18.

0:02:13.350,0:02:15.500
This is 18.

0:02:15.500,0:02:17.190
Carry or regroup the 1.

0:02:17.190,0:02:22.120
1 plus 0 is just 1.

0:02:22.120,0:02:23.010
And then finally.

0:02:23.010,0:02:25.380
You have the 6 in the[br]hundreds place.

0:02:25.380,0:02:28.840
Nothing gets added to it, so you[br]can just bring down that 6

0:02:28.840,0:02:30.190
and it's right there.

0:02:30.190,0:02:32.410
And you don't want to[br]forget the decimal.

0:02:32.410,0:02:37.730
And so when you add the numbers[br]you get 618.426, or

0:02:37.730,0:02:43.010
618 and 426 thousandths.

0:02:43.010,0:02:44.620
And we're done.
