Each American high school have different classes that they teach. My school teaches German, French, Sign language, Spanish, and Aeronautics. But, the basics are English, Math, P.E., History, and Science.

有一位網頁的回答出現語法錯誤。應該是Each American high school [has]，不知該網友是不是以英語為母語的

用word2003可以檢測出來

What do students in American high school study about math?

Do they study functions?
Do they study arithmetic/geometric sequence?
Do they study trigonometric functions?
Do they study to prove something about geometry?
