算術式的讀法：

※加法

1.在口語中的小數目的加法：用and代表“+”號，is或are 代表“=”

號。如：

Five and three is (or are) eight.

5 + 3 = 8

What’s seven and eight?

7 + 8 = ?

2.大數目的加法，或在比較正式的場合──用plus代表“+”號，

equals或is代表“?”號。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 = ?

※減法

1.在口語中的小數目的減法──可用以下兩種方式 ：

方法一：被減數+take away+減數+leaves (or is) +余數

方法二：減數+from+被減數+leaves (or is) +余數

Four from nine leaves (or is) five.

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

9 - 4 = 5.

2.大數目的減法或在比較正式的場合──用minus代表“-” 號，

equals代表“?”號。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.口語中小數目的乘法──第二個數目用復數形，等號用are 表示。

如：

What are three tens?

3 x 10 = ?

Five eights are forty.

5 x 8 = 40

2.大數目的乘法用times代表“x ”號，is或makes代表“=”號;在比較

正式的場合用multiplied by代表“x ;”號，equals代表“?”號。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.

※除法

1.小數目的除法有兩種方式：

方法一：用divided by 代表除號，equals代表“?”號。

方法二：除數+into+被除數+goes+余數──用于會話中。

Three into eighteen goes six.

or: Eighteen divided by three equals six.

18 除以3 = 6.

2.大數目的除法同方法一。

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

equal?

667 除以23 = ?
