Today I heard an interesting story from my mother.
My mother had been in America for a year. And she went to the local high school.
Both Japan and America study Math in high school.
I heard that American Math was easier than Japanese Math in those days.
Now it probably has been easy to study American Math.
Is it true? Studying Math in my high school is difficult for me.
I am studying about ' sine, cosine, tangent'.
What have you studied about Math when you were high school student in America or other countries?
