Hello, my name's Ronnie, I am going to teach you about math.I hate math, it's really confusing.
大家好，我是 Ronnie，我要教你们数学。我讨厌数学，搞不懂它。
I am going to teach you some easy expressions about math.I am NOT going to teach you math!
我要教你们一些关于数学的简单表达。我不是要教你们数学！
You can teach me math, because...can I do it?I remember being a child, being a teenager, and being a now-ager and math terrifies me.
你们可以教我数学，因为......你猜我会不会？我记得我小时候，青少年的时候，以及到了现在这个年纪，数学对我来说非常吓人。
There are too many numbers, too many things to remember, therefore I am an ESL teacher, not a math teacher.
要记住的数字，要记住的东西太多了，所以我就成了 ESL 的老师，而不是数学老师。
But I can teach you how to talk about it.So I will teach you the English you need to know to talk about math, bear with.
但是我可以教你们怎么表达。所以我会教你们谈论数学需要了解的英语，耐心听。

First thing: the very, very long word of this is "mathematics".We never have to say "mathematics", or "arithmetic".
第一件事，这个非常非常长的单词是 "mathematics" （数学）。我们从来不说 "mathematics（数学）" 或者 "arithmetic（算数）"。
If you are a very, very old person, living...you might be dead now...you would say "arithmetic".
如果你年纪非常非常大，生活在...... 你可能现在已经作古了，那你就会说 "arithmetic（算数）"。
Arithmetic is a very, very old word for math, or mathematics, that we do not use today.
"arithmetic" 是表示数学的一个非常非常古老的单词，我们如今都不用了。
It's too old, don't even worry about it.Don't worry about math!
这个词太老了，用不着担心它。不要担心数学！
So the first thing that I am going to teach you are the symbols, or how to the say the symbols.
我要教你们的第一个内容是这些符号或这些符号的叫法。
This sign (+) we say "add", this one (-) is "subtract", (/) "divide", and (x) "multiply".
我们把“+”这个符号叫做“加号”，“-”是“减号”，“/”是“除号”，“x”是乘号。
However, when we actually speak about math in a sentence in English, we don't use these words.
但是，我们真正用英语在句子中讲到数学时，我们用的不是这些词。
We use these red words.So instead of saying, for example: "5 add 7", we say "5 plus 7".
我们用的是这些红色的单词。所以，举个例子，我们不说“五加上七”，而说“五加七”。
So if you look at my equation here we say: "5 plus 7 equals...", "5 plus 7 equals 12."
所以请看我写在这儿的等式，我们会说“五加七等于......”，“五加七等于十二”。
I did it, I did it, I did it, I get an answer right.I hope that's right, 5 plus 7 equals 12, "ding", a point for me.
我做到了，我做到了，我做到了，我答对了。希望那是对的，五加七等于十二，“叮”，给我加上一分。
The next one's yours.We do not say "subtract", we say "minus", this is the sign (-) .
下一题你们来答。我们不说“减去”，而说“减”，它的符号是“-”。
So we would say "7 minus 1".Do you know the answer?If you know the answer, you've got homework.
所以我们说“七减一”。你们知道答案吗？如果你们知道答案，那我给你们个作业。
Go to YouTube, subscribe to my channel, write the answer to this in the comments.
打开 YouTube，订阅我的频道，在评论区写下这一题的答案。
You'll win, you'll win amazing prizes like trips to places, and money about things, it'd be a fabulous great time.
你们会赢大奖的，比如去某些地方旅行，买东西的钱，会特别棒的哦。
The next one is "divide".This is closer, we say "divided by".So we say "42 divided by 2".
下一个是“除”。这一个很相近，我们说的是“除以”。所以我们说“四十二除以二”。
This one's mine.42 divided by 2 is 22. (21! )The last one is "multiply".
这一题交给我。四十二除以二是二十二。（二十一！）最后一个是“乘以”。
It looks like an "z" or an "x", so you might say "9 x 7".We have to say "9 times 7".I don't know why "times" is an "x".
它的符号和 "z" 或 "x" 很像，所以可以说 "9 x 7"。我们要说“九乘七”。我不知道为什么“乘”要用 "x" 表示。
It's math, math is difficult and complicated and hard, but I'm going to teach you a trick.
这是数学啊，数学就是又难又复杂的，不过我要教你们一个小技巧。
My Grade 4 teacher taught me this.This is the only thing that I can do, like magic for math.
这是我四年级的老师教我的。这是我能做的唯一一个数学魔法。
If you want to figure out what 9 times something is, up to 10, you are going to take your fingers, and you're going to count.
如果你想算出来九乘某个数字是多少，十以内哦，那就把你的手指拿出来，掰着手指算。
For example, if I want to do 9 times 7, I do this: one, two, three, four, five, six, seven, and I put number seven down.
举个例子，如果我想算“九乘七”，我会这么做：一、二、三、四、五、六、七，然后把数字七放下来。
I have one, two, three, four, five, six, and three.Oh, magically, the answer is 63.Let's try again, 9 times 9.
我就有了一、二、三、四、五、六和三。魔法一般，答案就是六十三。我们再来试一下，“九乘九”。
So count on your fingers, one, two three, four, five, six, seven, eight, nine.
用手指算，一、二、三、四、五、六、七、八、九。
Put number nine down.You count how many fingers you have here.I have...oh, I have two thumbs.
把数字九放下来。数一数这里有多少根手指。我有......哦，我有两个拇指。
It doesn't matter, I have eight fingers here, and one here, the answer for 9 times 9 is 81.
这不重要，这里有八根手指，这里一根，所以“九乘九”的答案就是八十一。
Yes! Nine times tables, ask me anything, up to 10, up to 10, past 10 I've run out fingers, can't use my toes.
没错！九乘数字，随便问，十以内的，超过十我的手指就不够用了，也不能用脚趾头啊。
I don't even have toes, I don't even have legs, I am just floating here, teaching you math (ematics) .See you later.
我甚至都没有脚趾头，我甚至都没有腿，我就飘浮在这里教你们数学。下次见。
