متن انگلیسی درس
In this lesson we’ve talked about order things in sequence.
We’ve talked about dates we’ve talked about symbols.
Now let’s talk about numbers.
Now I know this lesson might be not as interesting a little little boring compared to the other lessons but it’s very important basic stuff.
Let’s go through basically how we can say numbers will move pretty quickly so that it’s not too hopefully not too dry.
One very very important thing to remember when it comes to numbers is all you have to do to say numbers clearly is group them in threes not including this decimal but the group them in threes and within each group of three between commas you just say the number.
So this would be I think you can probably guess one hundred and seven.
This would be three hundred and forty nine and the best way to know how to say a very big number is to count commas.
That’s really all you have to do.
You need to know how to say the number between zero and nine hundred ninety nine.
OK.
And you need to know how to count commas and you need to know what each of these commas means or what each of them represents.
This is thousand the first comma is thousand.
The second one is million.
The third one is billion.
And if you really want to know the next one is trillion but you don’t often need to say that.
OK.
So a thousand million billion if there are three commas you’re going to say billion then million then thousand.
If there are two commas you’re going to say million and then thousand.
If there is only one comma then you’re just going to say thousand.
OK.
That’s all you need to know if there are no commas then you don’t need to say any of them and you just say either.
Hundred or if it doesn’t have one hundred then we don’t even need to talk about that because you already know.
OK.
Count commas.
The other thing you need to know is this.
You do not need to add and between every number that makes it much more complicated.
You don’t need to do that.
You usually only need to use and if there is a zero in front of the last number in front of the very end of the number.
That’s the only time you usually need to use an OK.
So for example this might be one hundred seven.
You don’t have to say and but you could say one hundred and seven one hundred and seven.
This might be one thousand and seven in fact you should probably say one thousand and seven.
If you say one thousand seven it’s OK it’s OK but that’s when you would usually use and otherwise don’t do it.
It just makes it harder and you have more to think about.
OK.
The last thing that you need to know is after this show we say dot point.
Period after this point O P O I N T.
And we say point point after that.
Just say the number.
You don’t need to think about hundreds thousands millions or anything just say the number directly.
So let’s go through these.
OK.
This one one hundred and seven one hundred and seven.
This one one hundred seventy one hundred seventy.
Next one one thousand and seven one thousand and seven.
OK one thousand seventy one thousand seventy.
You can say one thousand and seventy if you want to.
You don’t have to.
OK.
This one one thousand seven hundred one thousand seven hundred one thousand seven hundred and one one thousand seven hundred and one.
OK.
Let’s get a little bigger.
Seventeen thousand.
Because there’s one comma.
Seventeen thousand five hundred eighty seven.
Don’t need to use end at all.
Then we can say it more quickly seventeen thousand five hundred eighty seven.
Seventeen thousand five hundred eighty seven.
You have to be able to say numbers very quickly.
Seventeen thousand five hundred eighty seven.
Seventeen thousand five hundred eighty seven should be very natural.
Very easy immediate.
OK.
Numbers are getting bigger but it doesn’t get harder.
OK.
One hundred seven thousand one hundred and seven point 1 0 7 7 0 1.
Easy.
1 0 7 7 0 1.
Can we say 1 0 7 7 0 1.
Yeah.
That’s OK you can say that 1 0 7 7 0 1.
No problem.
OK.
Now we have one two three three commas.
So that means we need to say billion.
Million and thousand.
OK.
So let’s try this very easy 1 billion one hundred seventy one million one hundred seventy thousand seven hundred and one point one three.
Very easy one billion one hundred seventy one billion one hundred seventy thousand seven hundred and one point one three.
Very simple.
OK last one.
Well it looks so long so scary but it’s actually not it’s actually not.
I realized that I’ve killed all the comments.
But I can read it without.
And I think you can too.
All right three hundred forty nine billion two hundred thirty million four hundred sixty seven thousand three hundred and four point seven six five three hundred forty nine billion two hundred thirty million four hundred sixty seven thousand three hundred and four point seventy six five practice that until it’s really easy go online just read an article and find some numbers big numbers small numbers and just practice saying them again and again follow the simple rules that we just talked about remember how many commas you see is the words that you need to say this this or this.
Remember that after the decimal you don’t need to think about hundreds or thousands.
And remember that usually we don’t use and unless there is a zero in front of the last number.
And if you remember those things you don’t need to know anything else.
The most important thing is that you get fast at this when it comes to numbers you shouldn’t have to think for a long time about just how to say the number.
It should be automatic.
Should come out of your mouth completely naturally.
All right.
So hopefully that’s relatively easy.
Practice it until it’s really smooth and you can speak and say numbers without thinking.
Now we’re going to quickly go on and talk about math.
