C1357 Junior High School Mathematics Problem

"Right, is Snowy home?" Yang Tao asked.2

"She's at home, doing her homework. She doesn't want to go to class, so I'm afraid that she might fall behind in her studies. I bought her an exercise book and started writing at home." Hang Xiaoyu said.

"Take me to see it." Yang Tao said.

After entering the room, he saw Hang Xiaoyu's father. Yang Tao took the initiative to greet him. He was also clear about the matter between Yang Tao and Hang Xiaoyu. He also knew the family situation, and he could not find fault with Yang Tao, his son-in-law.

He came to Hang Xiaoxue's room and saw her doing her homework. Yang Tao walked over and saw Hang Xiaoyu staring blankly with her hands under her chin. He smiled and said, "Your sister told you to do your homework. Why are you so lazy here?"

"Who's slacking off? I'm stuck on a topic and am still thinking." Hang Xiaoxue said.

"Yeah, let me see. I'll help you deal with it." Yang Tao said.

"My sister doesn't know, do you know?" Hang Xiaoxue said.

"It's impossible for him to not know the topics of the junior high school." Yang Tao said.

"I've been throwing away books for too long. I can't remember most of the formulas. Besides, the questions for junior high are very difficult." Hang Xiaoyu said, looking a little embarrassed.

"It's fine, let me take a look. I did very well in school." At that time, his grades were indeed very good, and he was ranked among the top few in terms of grades from junior high to senior high.

"Then show me." Hang Xiaoxue passed the homework to Yang Tao.

"Let the integer a, b, c (a ≥ b ≥ c) be the triangular length with a full and full a + b, and a foot a + b + c rs-ab-bc-ac = 13. The number of triangles with a circumference not exceeding 30 shall be obtained if the conditions are met." Yang Tao went silent after reading this question. His heart was in turmoil. Was his knowledge regressed, or were his junior high school questions so abnormal? What the hell was this? It felt like even high school students might not be able to write it.

But Hai Kou had already praised him. It wouldn't be too embarrassing if he said that right now. After thinking for a bit, he still didn't have any clues, so he asked, "Is there an answer?"

"I do, but I can't read the answers to the questions. Otherwise, it would be useless." Hang Xiaoxue said.

"Yes, as long as I have the answer." Hearing that there was an answer behind him, Yang Tao was relieved. His eyes moved and his gaze went straight through the paper and found the answer to this question.

"Brother-in-law, do you know how to?" Hang Xiaoxue asked.

"What's Little Snow's random name?" Although she knew that Yang Tao was very good to her, Hang Xiaoyu knew her identity. She was just Yang Tao's lover, how could she dare to ask for too much. However, Hang Xiaoyu didn't care about this and didn't regret her decision.

"I was just thinking. Since you want to know the answer that much, then Brother-in-law, I'll explain it to you. You should think this question should be solved this way." Then, Yang Tao picked up a pen and wrote on the paper.

Hang Xiaoyu's heart warmed when she heard that Yang Tao also called himself his brother-in-law. She looked at Yang Tao's serious expression and thought to herself, "The heavens are so nice to me to meet such a good man."

"So the final answer is thirteen." Yang Tao put down his pen and felt that he had achieved success.

"I'll see if I can." Hang Xiaoxue flipped open the last answer and compared it to Yang Tao's answer. She exclaimed, "That's right, even the process is the same."

"That's right, my answer is the standard answer, of course it's exactly the same." Yang Tao said proudly. How could it not be the same? I copied it according to the standard answer.

Yang Tao began to comment: "Although this question isn't difficult, it is a little out of order for junior high school students. Also, if you really do not know how to write the answers in the future, you can look at the answers and see how they are written. Try it yourself, this way you can get twice the result with half the effort."
