我們如何用英文表達 3 + 2= 5?這是一節英語課。 不是數學課! 在本課中,您將學習到基本數學符號和運算的英語詞彙:
“加減乘除”英文可以這樣說
加 (+) | plus |
減 (–) | minus |
乘 (X) | times/multiplied by |
除 (÷) | divided by |
等於 (=) | equals/is |
所以,3 + 2 = 5 可以表達為:
Three plus two equals/is five.
注意:不管主詞的數字是多少,也不管是加減還是乘除,運算符號都是用單數。
加 (+) 的英文
4 + 6 = 10
Four plus six equals ten.
120 + 90 = 210
One hundred and twenty plus ninety is two hundred and ten.
減 (-)的英文
6 – 4 = 2
Six minus four equals two.
注意,負號 (-) 和減去一樣,讀作 minus。
5 – 7 = -2
Five minus seven is minus two.
The temperature is minus 10 degrees. 氣溫是零下10度。
乘以 (X) 的英文
“乘”較常用的是 times (注意帶s的),也可以用 multiplied by, 按字面意思,即被某個數乘。
2 X 4 = 8
Two times four equals eight.
3 X 6 = 18
Three multiplied by six is eighteen.
除以 (÷) 的英文
除以 divided by ,按字面意思,即被某個數除。
9 ÷ 3 = 3
Nine divided by three is three.
20 ÷ 5 = 4
Twenty divided by five equals four.
加法,減法,乘法,除法的英文
上文我們解釋了算法表達式中的加減乘除 ,對於加法/減法/乘法/除法本身可以這樣表達:
加法 | addition |
減法 | subtraction |
乘法 | multiplication |
除法 | division |
Today we are going to practice addition. 今天我們要練習加法。
Let’s learn subtraction. 讓我們學習減法吧。
I’m good at multiplication. 我擅長乘法。
We are going to learn division. 我們要學習除法。
