中学数学教师們領着学生走一条康庄大道:“由整数走向分数,由正数走向負数,由有理数走向无理数,由实数走向虛数”。这是在那里扩张数系。同时又希望“整数的性貭分数也有,正数的性貭負数也有,有理数的性质无理数也有,实数的性貭虛数也有”。这是在那里因袭数性。 Middle school mathematics teachers lead students to take a broad road: “From integer to fraction, from positive to negative, from rational to irrational, from real to imaginary.” This is where to expand the number system. At the same time, I also hope that there are also “integer sex scores, positive sex negative numbers, and rational number nature, irrational numbers, and real number sex and imaginary numbers.” This is where the number of sex is there.
