算术式的读法：

※加法

1.在口语中的小数目的加法：用and代表“+”号，is或are 代表“=”

号。如：

Five and three is (or are) eight.

5 + 3 = 8

What’s seven and eight?

7 + 8 = ?

2.大数目的加法，或在比较正式的场合──用plus代表“+”号，

equals或is代表“?”号。如：

What does Two hundred and thirty-one plus a hundred and

sixty-three equal?

(or: What is Two hundred and thirty-one plus a hundred and

sixty-three?)

231 +163 = ?

※减法

1.在口语中的小数目的减法──可用以下两种方式 ：

方法一：被减数+take away+减数+leaves (or is) +余数

方法二：减数+from+被减数+leaves (or is) +余数

Four from nine leaves (or is) five.

or: Nine take away four leaves (or is) five.

9 - 4 = 5.

2.大数目的减法或在比较正式的场合──用minus代表“-” 号，

equals代表“?”号。如：

Four hundred and thirty-one minus a hundred and sixty-three

equals two hundred and sixty-eight, right or wrong?

431 - 163 = 268

※乘法

1.口语中小数目的乘法──第二个数目用复数形，等号用are 表示。

如：

What are three tens?

3 x 10 = ?

Five eights are forty.

5 x 8 = 40

2.大数目的乘法用times代表“x ”号，is或makes代表“=”号;在比较

正式的场合用multiplied by代表“x ;”号，equals代表“?”号。如：

What does fifteen times two hundred and sixty-nine make?

(or : What is fifteen times two hundred and sixty-nine?)

15 x 269 = ?

15 x 289 = 4335

15 multiplied by 289 equals 4335.

1.小数目的除法有两种方式：

方法一：用divided by 代表除号，equals代表“?”号。

方法二：除数+into+被除数+goes+余数──用于会话中。

Three into eighteen goes six.

or: Eighteen divided by three equals six.

18 除以3 = 6.

2.大数目的除法同方法一。

What does six hundred and sixty-seven divided by twenty-three

667 除以23 = ?
