19 thousands plus seven tens equals?
00:00:07.390 --> 00:00:11.630
How should we write 19 thousands with digits?
00:00:13.930 --> 00:00:20.090
We know that one thousand looks like this, a one followed by three zeros.
00:00:21.770 --> 00:00:25.070
And we have 19 thousands.
00:00:26.530 --> 00:00:30.900
This means that we need a 19 followed by three zeros.
00:00:33.480 --> 00:00:35.550
Now what about seven tens?
00:00:37.440 --> 00:00:41.540
We know that one ten is a one followed by a zero.
00:00:41.820 --> 00:00:44.770
And we have seven of those.
00:00:46.920 --> 00:00:51.770
Saying seven tens is the same thing as saying 70.
00:00:54.300 --> 00:00:59.170
From there, we need to add 19000 plus 70.
00:01:01.120 --> 00:01:06.770
19000 plus 70 equals 19070.
