0:00:00.000,0:00:00.550


0:00:00.550,0:00:05.020
Write six hundred forty-five[br]million five hundred

0:00:05.020,0:00:08.150
eighty-four thousand[br]four hundred

0:00:08.150,0:00:10.600
sixty-two in standard form.

0:00:10.600,0:00:13.000
So let's tackle this[br]piece by piece.

0:00:13.000,0:00:16.059
So the first part we[br]have six hundred

0:00:16.059,0:00:18.703
and forty-five million.

0:00:18.703,0:00:21.660


0:00:21.660,0:00:22.580
So let's think about that.

0:00:22.580,0:00:23.900
So we have six hundred[br]and forty-five.

0:00:23.900,0:00:26.940


0:00:26.940,0:00:28.790
But it's not just six[br]hundred forty-five.

0:00:28.790,0:00:31.540
We have six hundred forty-five[br]millions.

0:00:31.540,0:00:37.960
So we could view that as[br]645 times 1,000,000.

0:00:37.960,0:00:41.410
One million is one followed[br]by six zeroes.

0:00:41.410,0:00:44.940
So this piece right here is[br]this right over here.

0:00:44.940,0:00:48.840
That is six hundred and[br]forty-five million.

0:00:48.840,0:00:50.350
And what is that when[br]we write it out?

0:00:50.350,0:00:53.675
If we were to multiply this[br]out, this is equal to-- it

0:00:53.675,0:00:57.800
would be 645 times this 1 with[br]six zeroes behind it.

0:00:57.800,0:01:01.920
So this would be equal to 600--[br]I'll write it like this.

0:01:01.920,0:01:07.690
This is equal to 645, and then[br]we have our six zeroes.

0:01:07.690,0:01:10.560
One, two, three, one,[br]two, three.

0:01:10.560,0:01:13.860
That's just this part[br]of the number.

0:01:13.860,0:01:16.510
And I'm going to do it kind[br]of slow and do all of the

0:01:16.510,0:01:18.710
different parts of the problem,[br]but once you get some

0:01:18.710,0:01:20.610
practice, you'll find that these[br]are a bit second nature,

0:01:20.610,0:01:22.240
and you won't have to go through[br]all of these steps.

0:01:22.240,0:01:24.240
You'll just be able to[br]write the number.

0:01:24.240,0:01:25.790
Now, let's move on[br]to the next part.

0:01:25.790,0:01:28.680
We have five hundred[br]and eighty-four.

0:01:28.680,0:01:30.010
Let me write that down.

0:01:30.010,0:01:33.700


0:01:33.700,0:01:34.300
Well, I'll write it like this.

0:01:34.300,0:01:40.070
584 thousand.

0:01:40.070,0:01:42.100
So let me write the thousand.

0:01:42.100,0:01:43.760
So 584 thousand.

0:01:43.760,0:01:47.300
So it's 584 times 1,000.

0:01:47.300,0:01:48.870
And what's that going[br]to look like?

0:01:48.870,0:01:51.600
So that's this whole[br]part right here.

0:01:51.600,0:01:55.400
So 584 times 1,000[br]is equal to what?

0:01:55.400,0:01:59.840
Well, it's going to be 584 with[br]three zeroes behind it,

0:01:59.840,0:02:01.863
or you could view it as 584[br]times the 1, and then you're

0:02:01.863,0:02:04.010
going to have three zeroes[br]in the final answer.

0:02:04.010,0:02:11.620
So it's going to be 584,000.

0:02:11.620,0:02:13.400
We have our three zeroes[br]at the end.

0:02:13.400,0:02:15.030
584, three zeroes.

0:02:15.030,0:02:16.250
So that's that part.

0:02:16.250,0:02:22.910
And then finally, we have four[br]hundred sixty-two, and that's

0:02:22.910,0:02:24.960
just 462, straight up.

0:02:24.960,0:02:28.330
You could view it as 462 ones.

0:02:28.330,0:02:31.280
So then you just[br]have 462, which

0:02:31.280,0:02:35.280
obviously equals just 462.

0:02:35.280,0:02:38.430
Now our number is all[br]of these combined.

0:02:38.430,0:02:45.450
It is 645,000,000 and[br]584,000 and 462.

0:02:45.450,0:02:48.000
So one way to think about it[br]is that you could add these

0:02:48.000,0:02:49.330
three numbers.

0:02:49.330,0:03:08.300
So if we were to add them,[br]we get 645,584,462.

0:03:08.300,0:03:10.570
Now, I said it'll become a[br]little bit of second nature to

0:03:10.570,0:03:13.230
you in a little bit, and the way[br]to think about that, the

0:03:13.230,0:03:16.040
easiest way to think about that,[br]is millions will have

0:03:16.040,0:03:18.600
six zeroes behind them,[br]thousands will have three

0:03:18.600,0:03:22.290
zeroes behind them, and just[br]regular numbers have no zeroes

0:03:22.290,0:03:23.350
behind them.

0:03:23.350,0:03:25.940
So what you can do when you[br]kind of want to learn it

0:03:25.940,0:03:28.020
second nature, you'll just look[br]at the six hundred and

0:03:28.020,0:03:33.060
forty-five million, so you'll[br]write 645, and you'll kind of

0:03:33.060,0:03:35.320
keep in the back of your mind[br]that you're going to have to

0:03:35.320,0:03:38.310
have six more digits to[br]the right of this.

0:03:38.310,0:03:41.720
And then you say five hundred[br]and eighty-four thousand, so

0:03:41.720,0:03:44.030
then you have your five hundred[br]and eighty-four

0:03:44.030,0:03:50.320
thousand, so then you write that[br]down, 584,000, keeping in

0:03:50.320,0:03:51.620
mind that you're going to[br]need three digits to

0:03:51.620,0:03:52.530
the right of that.

0:03:52.530,0:03:55.470
And so if they didn't tell us[br]462, we would just put three

0:03:55.470,0:03:58.270
zeroes here, and that would also[br]fulfill the six zeroes we

0:03:58.270,0:04:00.490
need behind 645,000,000.

0:04:00.490,0:04:04.830
But then they tell us 462, so we[br]just write that right here.

0:04:04.830,0:04:06.350
462.

0:04:06.350,0:04:08.467
