1.3565 plus 2.252 is equal to blank rounded to the nearest thousandth.
00:00:10.990 --> 00:00:18.680
Before we round anything, we need to add these two values.
00:00:18.710 --> 00:00:27.120
We start by lining up their decimal points and making sure all the place values are in line.
00:00:27.120 --> 00:00:46.600
Beginning all the way on the right in the ten thousandths place, we add five plus zero equals five, six plus two equals eight, five plus five equals 10.
00:00:47.520 --> 00:00:52.760
Write down the zero, carry the one in the tenths place.
00:00:52.850 --> 00:00:57.020
One plus three plus two equals six.
00:00:58.110 --> 00:01:04.460
Bring down the decimal and then our units one plus two equals three.
00:01:05.600 --> 00:01:11.430
When we add these two numbers together, we get 3.6085.
00:01:11.460 --> 00:01:15.660
There’s an eight in the thousandths place.
00:01:15.690 --> 00:01:24.240
And we look to the right to the ten thousandths place to find out if we should round up or down.
00:01:24.240 --> 00:01:29.600
Since there’s a five in the ten thousandths place, we need to round up.
00:01:29.630 --> 00:01:31.070
This eight becomes a nine.
00:01:31.070 --> 00:01:36.910
And the values to the left of the nine do not change.
00:01:36.910 --> 00:01:38.060
We just bring those down.
00:01:38.060 --> 00:01:46.720
To the nearest thousandth, this addition problem gives us 3.609.
