In today's video I'm going to look at some math.

在今天的視頻中，我將看一些數學知識。

Now, I know this is an English site, don't worry, I'm not actually going to do any math.

現在，我知道這是一個英語網站，別擔心，我其實不會做任何數學。

Philosophy and English major, so math not my favourite, but I will give you some math

哲學和英語專業，所以數學不是我的最愛，但我會給你一些數學。

terminology, words that you need if you're going to do math.

術語，單詞，你需要 如果你要做數學。

Now, a lot of you might be engineers or you might be students who came from another country

現在，你們中的很多人可能是工程師，也可能是來自其他國家的學生。

to an English-speaking country, and you go to math class and you know the math, but you're

到一個英語國家，你去上數學課，你知道數學，但你是

So this is what we're looking at, terminology, only the words that you need to go into a

所以這就是我們要看的，術語，只有你需要進入的詞，才是

math class or to do some math on your own.

We're going to start with the very basics.

I'm just going to give you some ways to talk about them, and then we'll move on to some

我只是給大家講一些關於它們的方法，然後我們再繼續講一些。

So, you know the four basic functions: "addition", "subtraction", "multiplication", and "division".

所以，你知道四個基本功能。"加法"、"減法"、"乘法 "和 "除法"。

What you need to know is ways to say an equation.

你需要知道的是方程的說法方法。

that's also an equation which I'm not even going to get into.

這也是一個方程式，我甚至不打算進入。

You can say: "1 plus 1", "plus", of course is "+" symbol, that's the plus symbol.

你可以說："1加1"。"1加1"，"加"，當然是 "+"號，就是加號。

2 means the total, is also called the "sum".

Now, you can also say: "The sum of 1 and 1 is 2."

現在，你也可以說："1和1的總和是2。"1和1的總和是2."

You can also just say, without this part: "1 and 1 is 2."

你也可以直接說，沒有這部分，"1和1是2"。"1和1是2"

So you don't need the plus, you don't need the equal; you can use "and" and "is", but

所以你不需要加號，不需要等號，你可以用 "和"、"是"，但

Everybody will understand you're making...

抱歉，我是在做加法，不是在做。是做加法，不是做。

如果你把1和1相加，就會得到2。

Okay? So: "add" and "get", other words you can use to express the equation.

好嗎？那麼，"加 "和 "得"，"加 "和 "得"，你可以用其他詞來表達這個等式。

Now, if you're doing math problems, math problems are word problems.

現在做數學題的話，數學題就是文字題。

I know a lot of you have a hard time understanding the question because of the words, so different

我知道你們很多人很難理解這道題，因為文字，所以不同

ways to look at these functions using different words, different verbs especially.

用不同的詞、不同的動詞，特別是用不同的詞來看這些函數的方法。

If we look at subtraction: "10 minus 5 equals 5".

如果我們看減法。"10減5等於5"。

"5", the answer is also called the "difference".

For addition it's the "sum", for subtraction it's "difference".

對於加法是 "和"，對於減法是 "差"。

Or: "10 deduct"-means take away-"5", we can also say: "Take 5 away"...

或："十扣"--意思是拿走--"五"，我們也可以說。"拿走5"...

哦，我忘了一個詞在這裡。對不起，我忘了一個詞。

"10 subtract 5", you can say: "gives you 5",

"10減去5"，你可以說。"給你5"。

對不起，我不得不考慮這個問題。

So: "Take 5 away from 5, you get 5", "Take 5 away from 5, you're left with",

所以，"從5中取5，你得到5"。"從5中拿走5，你就得到5"，"從5中拿走5，你就剩下"。

Okay, so again, different ways to say the exact same thing.

好吧，所以再次，不同的方式說完全相同的事情。

So if you see different math problems in different language you can understand what they're saying.

所以，如果你看到不同語言的數學題，你就能明白他們在說什麼。

"5 times 5", that's: "5 times 5 equals 25".

"5乘以5"，就是。"5乘以5等於25"。

"25" is the "product", the answer to the multiplication, the product.

"25 "是 "積"，是乘法的答案，是積。

"5 multiplied by 5", don't forget the "by".

"5 multiplied by 5 is 25", "is", "gives you", "gets", etc.

"5乘以5是25"，"是"，"給你"，"得到 "等。

"9 divided by 3 equals 3", "3", the answer is called the "quotient".

"9除以3等於3"，"3"，答案叫做 "商"。

I don't have a very pretty "q", but it's a "q".

我的 "q "不是很好看，但它是一個 "q"。

"3 goes into... 3 goes into 9 three times",

so you can reverse the order of the equation.

所以你可以把等式的順序倒過來。

In addition, subtraction, multiplication...

Well, actually addition and multiplication you can reverse the order and it says the

嗯，其實加法和乘法你可以把順序反過來，上面寫著

Here you have to reverse the order: "goes into" as opposed to "divided by",

這裡你要把順序顛倒過來。"進入 "與 "除以 "的順序相反。

so pay attention to the prepositions as well.

Sorry. "3 goes into 9 three times", there's your answer.

對不起，"3進入9的三次"，這就是你的答案。"3進入9的三次"，這就是你的答案。

"10 divided by 4", now, sometimes you get an uneven number.

"10除以4"，現在，有時你會得到一個不均勻的數字。

So: "10 divided by 4" gives you 2 with a remainder of 2, so: "2 remainder 2".

所以："10除以4 "得2，有餘數為2，所以"10除以4 "得到2，餘數為2，所以："2除以2"。

Sometimes it'll be "2R2", you might see it like that.

有時會是 "2R2"，你可能會看到這樣。

So these are the basic functions you have to look at.

所以這些是你必須要看的基本功能。

Now we're going to get into a little bit more complicated math things.

現在我們要進入更復雜一點的數學事情。

We're going to look at fractions, exponents, we're going to look at some geometry issues,

我們要看分數，指數，我們要看一些幾何問題。

Okay, so now we're going to look at something else.

好了，現在我們要去看看別的東西。

We're going to look at fractions, exponents, and decimals.

我們要研究分數、指數和小數。

Again, all of you know these things even from high school, even before high school, primary

同樣，這些東西你們都知道，甚至從高中開始，甚至在高中之前，小學就知道了

A "fraction" is basically a partial number; it's not a whole number.

"分數 "基本上是一個部分數，它不是一個整數。

It's a part of, that's why it's called a fraction.

You have two parts to this fraction, you have the "numerator", "nu-mer-a-tor", and then

這個分數有兩個部分，你有 "分子"，"nu-mer-a-tor"，然後是

you have the bottom part which is the "denominator", "de-nom-in-at-or".

你有最下面的部分，這是 "分母"，"de-nom-in-at-or"。

Now, the thing to know about fractions, now, how to add them, how to multiply them, that's

現在，關於分數，現在要知道的是，如何加法，如何乘法，這是

a math lesson, we don't need to know that.

一堂數學課，我們不需要知道。

What you might have some trouble with is pronunciation.

你可能會有一些問題，就是發音。

So: "5 over 12", we don't say: "5 over 12", we say: "Five twelfths",

所以說："5比12"，我們不說："5比12"，我們不說： "5比12"，我們說："5比12"，我們說："5個12"。

"fths", so you have a lot of consonants here.

"fths"，所以你這裡有很多輔音。
