Jian Yiyi stood up quickly. “Teacher, it's me.”

Sun Dasheng looked at Jian Yiyi and said, “I see that you scored full marks for the Mathematics examination this month. Come up and answer this question.”

As he spoke, Sun Dasheng looked at the name list and said, “Student Jian Ai also scored full marks. Which one of you is Student Jian Ai?”

Jian Ai stood up when she heard this. Sun Dasheng saw that the two of them were sitting at the same table and was stunned. Their surnames were Jian? Could they be sisters?

However, on second thought, if they were sisters, why would one of them have two syllabuses in her name while the other has three? That shouldn't be the case.

“Come up and solve this question too.”

Jian Ai and Jian Yiyi looked at each other and walked up to the rostrum.

“d.a.m.n, they scored full marks for Mathematics? Are they crazy?”

“That's right. The monthly Mathematics examination questions are so difficult. There are at least five options for multiple-choice questions, and they got them all correct?”

At this moment, the two girls surnamed Jian had undoubtedly become monsters in their hearts.

Jian Ai and Jian Yiyi stood in front of the blackboard with chalk in their hands. They didn't start to solve the question but were thinking about it. The students below were also thinking. Some of them had some ideas, but most of them had question marks on their faces.

“Just try your best. It's fine if you can't solve it. This question is indeed a bit beyond your scope of knowledge.” Sun Dasheng tried to relieve the pressure on the two students.

At this moment, Jian Yiyi moved first. She pinched the chalk with her two jade-like fingers and started to solve it quickly. Surprisingly, she had beautiful handwriting.

Jian Yiyi's train of thought was very clear and smooth. Sun Dasheng stood at the side and couldn't help but nod as he read. In the end, Jian Yiyi listed fourteen rows of equations and finally obtained an answer: X = 5.

On the other side, Jian Ai started to move. Many people frowned. Was Jian Ai copying Jian Yiyi's answer?

However, just as everyone was puzzled, Jian Ai had already solved the question. Compared to Jian Yiyi's lengthy fourteen rows of equations, Jian Ai only used five rows, but the final answer was X = 5!

Even Sun Dasheng was stunned. Only Year Three students would know how to solve the question using Jian Ai's method.

“The answer is the same?”

“What does the second formula mean? I've never learned it…”

“I don't know. It's so flashy that I can't understand it.”

Sun Dasheng came back to his senses and looked at Jian Ai and Jian Yiyi with admiration. He said, “Very good. Everyone, clap and encourage the two female students.”

Everyone applauded when they heard this. Sun Dasheng then explained, “The two of you used two different ideas to solve this problem. Jian Yiyi's idea is the knowledge point I told you just now. The method Jian Ai used seems simple, but it's actually an even more difficult knowledge point. It's a formula in the third year's Mathematics textbook…”

Everyone was shocked when they heard that.

Knowledge points for Year Three? They were only in their first half of the Year One semester. Jian Ai even knew the formula for Year Three?

No wonder she could score full marks. Mathematics in Year One was as simple as one plus one in her eyes.

Lin Yi immediately turned to the left. Although Jian Yiyi was sitting in the middle and blocking his vision, his eyes were still filled with admiration. Unexpectedly, Jian Yiyi turned around at this moment and met Lin Yi's gaze. Lin Yi's expression met hers.

The admiration and softness in the bright and handsome boy's eyes made Jian Yiyi blush and turn her head away.
