Crossing the Homeland

Chapter 297

Tang Tingyue was taken aback. She had heard her brother talk about that question before, and her brother said that generally an acre of land is from [-] to [-], and most of the fields in her family are the same, so she wrote it down.Now that Xia Junyan changed the number, Tang Tingyue got stuck immediately.

Xia Junyan asked again: "Today there is one mu of land, 24 steps wide, how much is it?"

The stage was silent.

The female students all stared at Tang Tingyue, and the ladies on both sides also looked at the lady of the Tang family. Whoever speaks out at this moment is a fool!Although it was only a short time, Tang Tingyue felt that the days seemed like years.

Xia Junyan waited for a while, but she still couldn't wait for Tang Tingyue's answer, so she said, "I know what's happening, but I don't know why. It's best to avoid half-knowledge in learning." She raised her hand to signal that she could sit down.

15 multiplied by 16 knows the answer, but if it is 8 times 30, I don’t know it, and if it is divided, I don’t know it even more... Xia Junyan really doesn’t know how to evaluate this Miss Tang.

Let's just say it's...courageous.

Xia Junyan also learned about the mathematics level of this group of female students through Tang Tingyue. She knew about addition and subtraction. Instead of multiplication and division, she only remembered all the fixed numerical answers, and they memorized them through arithmetic poems. Know how to multiply, divide, and carry.

Come on, there is no need to continue to drag classical Chinese.Xia Junyan resolutely avoided shortcomings. When it comes to poetry and fu, her classical Chinese proficiency is definitely not the match of these ladies. Maybe she can directly sacrifice the finished products of future generations of great writers, but wouldn't that be the same as Tang Tingyue?I only know the conclusion, but I don't understand the rules at all. If you meet someone who really knows, ask her the bottom line, the shame and embarrassment are not something that can be digested normally.

If you want to understand multiplication and division, you naturally start with addition.The discussion with Mo Xueba was about algebraic geometry. Here, the difficulty level dropped so that Xia Junyan was caught off guard.

But she is also very serious about teaching, she does not know how to teach arithmetic in ancient times, and she is not a teacher, so she naturally began to imitate the classrooms of modern elementary schools. The basic knowledge taught in the nine-year compulsory education of the Chinese Dynasty is still very firm!
Teaching mathematics is not the same as other subjects, it needs a lot of examples to prove.Chen Shuyun wanted to interrupt several times, but Xia Junyan's teaching was systematic, link after link, and the female students below were engrossed in listening, so she couldn't interrupt at all.

When Xia Junyan was free, it was time for the female students to do it by themselves.Doing math problems is the most annoying thing to be interrupted and talked by others. Chen Shuyun can only stay in the lecture hall, looking at Xia Junyan with an unhappy face.

However, the background of this group of female students is not bad. Xia Junyan found that the nine-nine multiplication table already exists in this era, but for the multiplication and division of more than two digits, the single digit is multiplied by two digits or three digits. Abacus, so... Basically, non-professionals will not learn it on purpose. As for the formula, power, etc., Xia Junyan feels that she will not talk about it ten times.

At the end of the course, Xia Junyan directly asked the multiplication of three-digit numbers as the last question.After she finished her calculations, she turned her head and saw Mrs. Chen standing in the distance. She almost dropped the chalk in her hand in fright.

But everyone was looking at her, not paying attention to the movement behind her.As soon as Mr. Chen made a fool of himself, Mrs. Chen entrusted him to go back.Xia Junyan quickly recovered her expression, as if nothing had happened.
