It's really confusing. I am going to teach you some easy expressions

這真令人困惑，我會教一些關於數學的

about math. I am NOT going to teach you math! You can teach me math,

簡單表達方式，但我不會教你們數學，你們可以教我

because... can I do it?

因為...我能解出正確答案嗎？

I remember being a child, being a teenager, and being a now-ager and math

我記得從小學、中學到現在，我一直很

terrifies me. There are too many numbers, too many things to remember,

畏懼數學，有太多的數字和公式要背

therefore I am an ESL teacher, not a math teacher. But I can teach you how

所以我才成為ESL老師而不是數學老師，但我可以教你們

to talk about it.

怎麼說這些數字

So I will teach you the English you need to know to talk about math -- bear with.

我會教你們在談數學時必學的英文說法，耐心點

First thing: the very, very long word for this is "mathematics". We

第一件事，這個非常非常長的的字是「數學」

never have to say "mathematics", or "arithmetic". If you are a very, very old

我們從不說mathematics或是arithmetic，如果你是個

person, living... you might be dead now... you would say arithmetic.

年紀很大很大的人，你現在可能也死了，你可能會說arithmetic

Arithmetic is a very, very old word for math, or mathematics, that we do not

arithmetic是個非常非常古老的數學詞彙，mathematics也是，都不是我們

use today -- it's too old. Don't even worry about it. Don't worry about

現在會使用的，那太過時了，不需要太擔心，別擔心數學

math! So the first thing that I am going to teach you are the symbols, or

所以我要教你們的第一樣東西是數學符號

how to the say the symbols.

以及如何說這些數學符號

This sign "+" we say "add". This one (-) is "subtract", (/) "divide", and (x) "multiply"

這個符號我們稱為「加」，這個是「減」、「除」和「乘」

However, when we actually speak about math in a sentence in

但是，當我們平時在用英文談論數學時

English, we don't use these words. We use these red words, so instead of

我們不使用這些字，我們會用紅色的字

saying for example: "5 add 7"; we say "5 plus 7", so if you

在唸「5加7」時，我們會用plus而不是add

look at my equation here we say: "5 plus 7 equals"

看到這個題目，我們會唸「5加7等於」

"5 plus 7 equals 12." I did it, I did it, I did it. I get an answer right.

「5加7等於12」，我會了！我答對了！

I hope that's right.... 5 plus 7 equals 12 -- *ding* a point for me. The

希望答案是對的...5加7等於12，(叮)我加一分

next one's yours. We do not say "subtract", we say "minus". This is the sign (-)

下一題你來做，我們會說minus，而不是subtract，看這個標誌

So we would say "7 minus 1". Do you know the answer? If you

我們說「7減1」，你知道答案嗎？

know the answer, you've got homework.

如果你知道答案，有個功課要交給你

Go to You Tube, subscribe to my channel, write the answer to this in the

到You Tube訂閱我的頻道，在意見欄留下答案

comments. You'll win, you'll win amazing prizes like trips to places, and

你就可以贏得超棒的獎品，像是旅遊的機會

money about things, it'd be a fabulous great time. The next one is "divide".

那一定會是超美好的時光，下一個是divide

This is closer. We say divided by, so we say "42 divided by 2."

這個比較相似，我們唸除以，所以這是「42除以2」

This one's mine. "42 divided by 2 is 22." (21!)

這題我來算，42除以2是22 (不！是21)

The last one is "multiply". It looks like an "x" and you might

最後一個是相乘，看起來很像字母「x」所以你可能

say "9 x 7". We have to say "9 times 7". I don't know why

會說「9x7」，但正確應該唸「9乘以7」我不知道為什麼

"times" is an "x" -- it's math. Math is difficult and complicated and hard,

「相乘」要用x表示，數學很複雜、難懂而且困難

but I'm going to teach you a trick.

所以我要教你們一個小技巧

My Grade 4 teacher taught me this. This is the only thing that I can do, like

我的小學四年級老師教我的，是我唯一會的

magic for math. If you want to figure out what 9 times something is

像數學的魔法，如果你想知道9乘以什麼會接近10

up to 10... You are going to take your fingers, and you're going to count.

你會需要用到手指，然後你開始數數

For example, if I want to do 9 times 7, I do this: one, two, three, four,

例如，我要算9乘以7，我會這樣，1,2,3,4,

five, six, seven, and I put number seven down. I have one, two, three,

5,6,7，接著我把七往下擺，我有1,2,3,

four, five, six, and three. Magically, the answer is 63.

4,5,6和3，奇妙的，答案就是63

Let's try again. 9 times 9. So count on your fingers, one, two

再試一次，9乘以9，用你們的手指算，1,2

three, four, five, six, seven, eight, nine. Put number nine down. You

3,4,5,6,7,8,9，把9往下擺

count how many fingers you have here. I have, oh, I have two thumbs. It

現在來算你有幾隻手指，我有...我有兩隻大姆哥

doesn't matter. I have eight fingers here, and one here, the answer for

這不重要，我這裡有八隻手指，這裡有一隻，所以9乘以9

9 times 9 is 81.

答案是81

Yes! Nine times tables -- ask me anything up to 10, past 10 I've run out

太好了！隨便考我10以下的數字，超過10我的手指就不夠用了

fingers, can't use my toes. I don't even have toes.

不能用腳趾算，我根本沒有腳趾

I don't even have legs. I am just floating here, teaching you math(ematics). See you, later.

我甚至沒有雙腿，我現在正漂浮著教你們數學，下次見
