Ye Linlang looked at the paper in front of her and felt that it was too difficult. She put it aside and picked up a slice of cake to eat.
She had to admit that Jiang Miaomiao’s mother’s cooking skills were really great!
The salmon sushi roll from before was so good that it made people want to cry. This mango mousse cake was also like something made in a dessert shop!
Ye Linlang held the small piece of cake and suddenly looked at Jiang Qiran. When she saw the same food in the other person’s hand, Ye Linlang suddenly smiled.
It seemed that because of the food, the distance between her and Jiang Qiran had become much closer.
Jiang Qiran slightly raised his phoenix-like eyes. He glanced at the satisfied smile on Ye Linlang’s face and suddenly threw a sentence.
“What’s the matter? You can’t finish the test?”
Ye Linlang heard this and felt a little guilty for some reason. She nodded her head nervously and answered softly.
“Yes, I can’t figure out this trigonometric function problem.”
Jiang Qiran leaned his head over and his gaze quickly swept over the trigonometric function question.
“The odd to even changes, the sign depends on the quadrant. Don’t you understand such basic principles?”
Ye Linlang nodded in confusion. Then, she picked up the draft that she had just drawn and looked at it blankly.
“I know that, but the results I calculated don’t match.”
Jiang Qiran shook his head helplessly.
He picked up the paper and began to explain the question in detail.
Although Su Wan had always been lacking in mathematics, Jiang Qiran had probably only inherited his father’s mathematical brain, so these questions were not even an appetizer in Jiang Qiran’s eyes.
If it was not for the fact that he was teaching Ye Linlang the questions, he would usually figure out the answers in his head.
…
Jiang Qiran quickly wrote down the formulas and explained step by step. Soon, Ye Linlang also found a way.
“So that’s how it is! I finally understand where I was wrong just now!”
Looking at Ye Linlang’s shining black eyes, Jiang Qiran could not help but laugh.
Was there a need to be so excited?
It was only such a simple question.
And Ye Linlang clearly didn’t realize that her IQ was no longer zero in Jiang Qiran’s heart. She was probably going to become a negative IQ.
She excitedly approached Jiang Qiran and looked at the youth in front of her with great admiration, her eyes shining with stars.
“Qiran, you’re so amazing. I wanted to ask you earlier, how can you recite so many formulas? If it were me, I’m afraid I would have to flip through the mathematics textbook a few times.”
“Isn’t memorizing formulas the most basic of mathematical literacy? If you were to appear in the examination room with a math book, you won’t find the answer, but you would be invited out of the examination room instead.”
Ye Linlang pursed her lips. She lowered her head slightly, thinking that Jiang Qiran wouldn’t notice her mumbling.
“Isn’t memorizing the formulas just a last-minute effort?”
Ye Linlang didn’t believe that she wouldn’t be able to memorize it after only spending one or two days!
Unfortunately, Ye Linlang had underestimated Jiang Qiran’s hearing.
Jiang Qiran glanced at Ye Linlang coldly, and his voice was loud and clear.
“Do you think it’s that easy to cram at the last minute? The more you cram at the last minute, the worse it gets. Haven’t you heard this before?”
Ye Linlang’s face instantly froze.
Damn!
What kind of hearing was Jiang Qiran using!
She had said it so softly just now, but Jiang Qiran could hear it. This was too scary!
However, Jiang Qiran had exposed her complaint just now. Ye Linlang didn’t dare to talk back to him and immediately said yes.
“Qiran, you’re right! I also think that these formulas should be memorized normally! So I’ll try my best to memorize them seriously!”
“Are you sure that you’re memorizing them seriously?”
Ye Linlang coughed lightly, stood upright proudly, and even puffed out her chest!
“Of course! I’m very serious! I wasn’t flipping through the math book, and I still remember the formulas!”
Jiang Qiran shook his head in exasperation and amusement. He picked up the draft paper and pointed out Ye Linlang’s problem without holding back.
“Take a look at the trigonometric function formula you just listed. Both the plus and minus signs are wrong. If you can still answer correctly, then you are absolutely blind.”
Ye Linlang’s lackey smile immediately froze!
Heavens, it was exactly as Jiang Qiran said!
No wonder she couldn’t calculate correctly before. It was because the plus and minus sign was wrong!
One wrong step led to another. All the formulas that followed were further and further away because of this initial step.
SOB, sob, sob. Why did she always make such low-level mistakes?!
She was so embarrassed!
Ye Linlang cursed herself a little in her heart. However, she still tried to pretend in front of Jiang Qiran.
“I… I was just careless. I won’t repeat it again in the future.”
Jiang Qiran narrowed his eyes. He suddenly approached Ye Linlang and gave her a hard knock on the head!
“It hurts — I told you I would become stupid!”
Jiang Qiran’s handsome face was cold.
“If I don’t knock you a few times, you might make such a mistake again. How dare you use carelessness as an excuse?”
“If you became an accountant in the future and miss a plus or minus sign, or even a decimal point, do you know that it’s a loss of hundreds of thousands for the company?”
Ye Linlang pouted and touched her head with a bag of tears.
“I’m not going to be an accountant…”
Seeing that Jiang Qiran was still trying to criticize her, Ye Linlang quickly continued to cover his mouth.
“It’s not just an accountant. In the future, I won’t be a math teacher, cashier, scientist, experimenter, or anything like that!”
Jiang Qiran’s face was full of black lines when he heard that.
“Do you think others would dare to hire you when you’re so forgetful?”
Ye Linlang was originally very pleased with herself and almost listed all the occupations related to mathematics. Who would have thought that Jiang Qiran’s counterattack would be so powerful!
It was simply a one-hit KO!
Ye Linlang was helpless.
“Alright, alright. They don’t like me, and I don’t like them either. It’s fine if we dislike each other, right?”
Jiang Qiran didn’t want to bother with Ye Linlang anymore.
He directly took the cake from Ye Linlang’s hand.
“Hey, don’t you know that stealing food from others is very immoral? This is what Miaomiao gave me!”
Jiang Qiran ignored Ye Linlang, who had a face full of grief and indignation. Instead, he put the half-eaten cake aside and took out a math book from Ye Linlang’s bag.
With a bang, Jiang Qiran placed the math book in front of Ye Linlang.
“Page 221 of Unit 3. Start memorizing the math formulas of the trigonometric functions now. I’ll do a spot check in three minutes!”
Wait, why did Jiang Qiran remember so clearly? Where were the formulas?
Ye Linlang turned to page 221 in disbelief. As expected, it was really full of knowledge and formulas of trigonometric functions!
“Can you extend it to five minutes?”
Ye Linlang asked weakly.
And the youth’s handsome face was cold,
“Only three minutes. Otherwise, you can’t eat your cake and sushi.”
