After listening to the old elders, he was so angry that the primary and secondary education in Guangzhou has lost its ancestor's clothes. He said that the language behavior of our descendants was assimilated by foreign families, and the current usage of Cantonese in primary school students is far inferior to that in the early days of liberation. At that time, there were no slogans to promote Mandarin. Students could learn a lot of authentic Cantonese culture in class. He talked about a Cantonese dialect math question at that time-"Triangle ry co-hexagonal, triangle ry ?", Ask me if I know the answer. I read it several times and couldn't find any xuanjicang at the moment, "scratching my head ". Later, he explained a little. I woke up immediately. Haha, it was really clever!
This question is translated into vernacular, which means that triangle is a book, and ry is also a book. These two books add up to a total of six cents (hexagonal = six cents). Ask you now, if the triangle book is three cents, how much is the geometric book (the last ry =? The simplest arithmetic operation in the lower grades of primary school. It seems that I am worse than the primary school students at that time ~
