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 = ?
