The "I" and "A" after the numbers may be different from those in China. We can divide it into the first volume and the second volume ... Japanese high schools don't divide it like this, and mathematics should be studied step by step from senior one to senior three. Math A, Math B, Math C Greek letters and English letters have different connotations, but they are all gradual. Let me tell you the content, I guess you should understand.

Number I ... equation? Inequality, quadratic, trigonometric ratio

Number Ⅱ … complex prime number, 円の equation, triangle? Index? の Differential Integral of Integer and Integer

Number three ... limit, triangle? Index? Differential integration of numbers and numbers

. . . . . . .

Number A… set, accuracy, plane shape, proposition, theory

No. B… series, ベクトル

Quantity C… grade, quadratic curve の classification

It can be seen that I ~ III and A ~ C are separate systems. Senior one learns from me and A; Senior two studies ⅱ and B; The "I" and "A" of senior three students after learning numbers are different from those in China.
