Dialogue: 0,0:00:00.50,0:00:02.60,Default,,0000,0000,0000,,Now, let's do the exact\Nsame addition problem
Dialogue: 0,0:00:02.60,0:00:03.85,Default,,0000,0000,0000,,that we did in the last video.
Dialogue: 0,0:00:03.85,0:00:06.22,Default,,0000,0000,0000,,But I'm going to expand out\Nthese numbers so that we really
Dialogue: 0,0:00:06.22,0:00:07.81,Default,,0000,0000,0000,,understand what's\Ngoing on when we're
Dialogue: 0,0:00:07.81,0:00:09.43,Default,,0000,0000,0000,,doing all of this carrying.
Dialogue: 0,0:00:09.43,0:00:11.49,Default,,0000,0000,0000,,So this 5 is in\Nthe hundreds place.
Dialogue: 0,0:00:11.49,0:00:14.73,Default,,0000,0000,0000,,So it really represents\N5 hundreds or 500.
Dialogue: 0,0:00:14.73,0:00:17.67,Default,,0000,0000,0000,,3 represents 3 tens because\Nit is in the tens place.
Dialogue: 0,0:00:17.67,0:00:19.15,Default,,0000,0000,0000,,So it represents 30.
Dialogue: 0,0:00:19.15,0:00:23.00,Default,,0000,0000,0000,,And the 6, well, it just\Nrepresents 6 ones or 6.
Dialogue: 0,0:00:23.00,0:00:26.94,Default,,0000,0000,0000,,Likewise, this 3 represents 300.
Dialogue: 0,0:00:26.94,0:00:31.18,Default,,0000,0000,0000,,This 9 is 9 tens or 90.
Dialogue: 0,0:00:31.18,0:00:35.24,Default,,0000,0000,0000,,And this 8 just\Nrepresents 8 ones or 8.
Dialogue: 0,0:00:35.24,0:00:37.59,Default,,0000,0000,0000,,And now we can add these two up.
Dialogue: 0,0:00:37.59,0:00:42.14,Default,,0000,0000,0000,,Now let's start in the\Nright-most column-- this ones
Dialogue: 0,0:00:42.14,0:00:42.67,Default,,0000,0000,0000,,column.
Dialogue: 0,0:00:42.67,0:00:45.10,Default,,0000,0000,0000,,6 plus 8, we've\Nalready figured out,
Dialogue: 0,0:00:45.10,0:00:48.78,Default,,0000,0000,0000,,is equal to 14, which is\Nthe same thing as 10 plus 4.
Dialogue: 0,0:00:54.06,0:00:55.48,Default,,0000,0000,0000,,So let's write the\Npart that's not
Dialogue: 0,0:00:55.48,0:00:57.39,Default,,0000,0000,0000,,a multiple of 10 in\Nthis ones column.
Dialogue: 0,0:00:57.39,0:00:58.65,Default,,0000,0000,0000,,So let's put that 4 there.
Dialogue: 0,0:00:58.65,0:01:00.53,Default,,0000,0000,0000,,And the part that\Nis a multiple of 10,
Dialogue: 0,0:01:00.53,0:01:02.71,Default,,0000,0000,0000,,we can now carry into\Nthis tens column.
Dialogue: 0,0:01:02.71,0:01:04.100,Default,,0000,0000,0000,,And that's just to keep track\Nof it-- just to make sure
Dialogue: 0,0:01:04.100,0:01:06.60,Default,,0000,0000,0000,,that we don't lose\Nthat 10, we're
Dialogue: 0,0:01:06.60,0:01:08.23,Default,,0000,0000,0000,,putting it into the tens column.
Dialogue: 0,0:01:08.23,0:01:09.78,Default,,0000,0000,0000,,Now we can add all the tens.
Dialogue: 0,0:01:09.78,0:01:14.70,Default,,0000,0000,0000,,10 plus 30 plus 90, we've\Nalready figured out is 130.
Dialogue: 0,0:01:14.70,0:01:18.22,Default,,0000,0000,0000,,Well the part that is\Nnot a multiple of 100,
Dialogue: 0,0:01:18.22,0:01:21.36,Default,,0000,0000,0000,,we can write in this tens\Ncolumn-- so the 30 part.
Dialogue: 0,0:01:21.36,0:01:23.19,Default,,0000,0000,0000,,And then the part that\Nis a multiple of 100,
Dialogue: 0,0:01:23.19,0:01:24.81,Default,,0000,0000,0000,,we can put in the\Nhundreds column.
Dialogue: 0,0:01:24.81,0:01:27.73,Default,,0000,0000,0000,,So we could put the\N100 right over here.
Dialogue: 0,0:01:27.73,0:01:29.60,Default,,0000,0000,0000,,Notice, we've just\Ncarried the 1.
Dialogue: 0,0:01:29.60,0:01:32.11,Default,,0000,0000,0000,,But essentially, we've carried\N100, because we put a 1
Dialogue: 0,0:01:32.11,0:01:33.16,Default,,0000,0000,0000,,in the hundreds place.
Dialogue: 0,0:01:33.16,0:01:36.70,Default,,0000,0000,0000,,10 plus 30 plus\N90 is 100 plus 30.
Dialogue: 0,0:01:36.70,0:01:41.12,Default,,0000,0000,0000,,This is equal to 100 plus 30.
Dialogue: 0,0:01:41.12,0:01:42.41,Default,,0000,0000,0000,,That's all we've done.
Dialogue: 0,0:01:42.41,0:01:44.30,Default,,0000,0000,0000,,Now we can add the hundreds.
Dialogue: 0,0:01:44.30,0:01:49.00,Default,,0000,0000,0000,,100 plus 500 plus 300 we've\Nalready figured out is 900.
Dialogue: 0,0:01:49.00,0:01:51.52,Default,,0000,0000,0000,,So we can write it as 900.
Dialogue: 0,0:01:51.52,0:01:52.39,Default,,0000,0000,0000,,And we're done!
Dialogue: 0,0:01:52.39,0:01:54.64,Default,,0000,0000,0000,,We've figured out that\N500 plus 30 plus 6,
Dialogue: 0,0:01:54.64,0:02:02.06,Default,,0000,0000,0000,,plus 300 plus 90 plus 8, is\Nequal to 900 plus 30 plus 4,
Dialogue: 0,0:02:02.06,0:02:05.22,Default,,0000,0000,0000,,which is the same thing as 934.
Dialogue: 0,0:02:05.22,0:02:07.34,Default,,0000,0000,0000,,So hopefully this gives\Nyou a little bit more sense
Dialogue: 0,0:02:07.34,0:02:09.66,Default,,0000,0000,0000,,of what we're doing when we\N"carry the 1" every time.
Dialogue: 0,0:02:09.66,0:02:11.52,Default,,0000,0000,0000,,6 plus 8 is 14.
Dialogue: 0,0:02:11.52,0:02:12.94,Default,,0000,0000,0000,,We carried the 1.
Dialogue: 0,0:02:12.94,0:02:14.35,Default,,0000,0000,0000,,That 1 represents 10.
Dialogue: 0,0:02:14.35,0:02:15.93,Default,,0000,0000,0000,,It represents this\N10 right over here.
Dialogue: 0,0:02:15.93,0:02:17.38,Default,,0000,0000,0000,,Just so we don't\Nlose track of it.
Dialogue: 0,0:02:17.38,0:02:22.94,Default,,0000,0000,0000,,Then we say that 10 plus\N30 plus 90 is equal to 130.
Dialogue: 0,0:02:22.94,0:02:25.19,Default,,0000,0000,0000,,So that's 30 plus 100.
Dialogue: 0,0:02:25.19,0:02:28.22,Default,,0000,0000,0000,,Then we add the hundreds\Ntogether and we get 900.
