Ye Linlang looked at the test paper in front of her and felt that it was too difficult, so she simply put it aside and picked up a piece of cut cake to eat.
I have to say, Jiang Miaomiao’s mother’s cooking skills are really great!
The salmon sushi roll I had earlier was so good it made me want to cry, and this mango mousse cake looks like it was made in a dessert shop!
Ye Linlang held the small piece of cake in her hand and suddenly looked towards Jiang Qiran. Seeing the same food in that person's hand, Ye Linlang smiled slightly.
It seemed that because of these foods, the distance between her and Jiang Qiran was invisibly shortened.
Jiang Qiran raised his eyes slightly, glanced at the satisfied smile on Ye Linlang's face, and suddenly said something.
"Why, can't you finish the test paper?"
Ye Linlang felt a little guilty for some reason when she heard this. She nodded nervously and responded softly.
"Hmm, I can't figure out this trigonometric function."
Jiang Qiran leaned over and his eyes quickly swept over the trigonometric function problem.
"Odds change, evens don't change, the sign depends on the quadrant, don't you understand such basic principles?"
Ye Linlang nodded in confusion, then she picked up the draft drawing she had just drawn, her face blank.
"I know this, but the results I calculated, ABCD, don't match."
Jiang Qiran shook his head helplessly.
He picked up the paper and began to explain the questions in detail to the people in the courtyard.
Although Su Wan has always been lacking in mathematical ability, Jiang Qiran probably only inherited his father's mathematical mind, so these questions are not even appetizers in Jiang Qiran's eyes.
If he wasn't explaining the questions to Ye Linlang, he would usually be the kind of person who could figure out the answer after doing some calculations in his mind.
…
Jiang Qiran quickly wrote down the formulas and explained the solution step by step. Soon, Ye Linlang also found a solution.
"So that's how it is! I finally understand where I went wrong just now!"
Looking at Ye Linlang's glowing black pupils, Jiang Qiran couldn't help laughing.
Is it necessary to be so excited
It’s just such a simple question.
Ye Linlang obviously did not realize that in Jiang Qiran's heart, her IQ was no longer zero, and it was probably about to become negative.
She moved closer to Jiang Qiran excitedly, looking at the boy in front of her with great admiration, her eyes shining with stars.
"Qiran, you are amazing. I wanted to ask you before, how come you can recite so many formulas? If it were me, I would probably have to flip through the math textbook several times."
"Isn't being able to memorize formulas the most basic mathematical literacy? If you show up at the exam with a math book, you probably won't know the answer, but will be asked to leave the exam room."
Ye Linlang pursed her lips and lowered her head slightly, thinking that Jiang Qiran would not notice her mumbling.
"Isn't it possible to just learn the formula at the last minute?"
After spending a day or two memorizing it in shorthand, Ye Linlang didn't believe that she couldn't memorize it!
Unfortunately, Ye Linlang underestimated Jiang Qiran's hearing.
Jiang Qiran glanced at Ye Linlang coldly and spoke in a resounding voice.
"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 saying?"
Ye Linlang's face froze instantly.
I go!
What kind of hearing is this, Jiang Qiran!
She just spoke so softly that Jiang Qiran could hear it. This is too scary!
However, her complaint was exposed by Jiang Qiran, and Ye Linlang did not dare to talk back to him, and immediately said yes in a servile manner.
"Qiran, you're right! I also think these formulas should be memorized regularly! So I try my best to remember them carefully!"
"Are you sure you're memorizing it seriously?"
Ye Linlang coughed lightly, stood up straight proudly, and straightened her chest!
"That's right! I'm serious! Didn't I just not look at the math book? But I remember the formula too!"
Jiang Qiran shook his head in anger and amusement. He picked up the draft paper and pointed out Ye Linlang's problems bluntly.
"Look at the trigonometric formula you just wrote. The positive and negative signs are all wrong. If you can get it right, it must be a blind cat catching a dead mouse."
Ye Linlang's flattering smile suddenly froze!
Oh my god, it’s exactly the same as what Jiang Qiran said!
No wonder her calculations were always wrong before, it was because the positive and negative signs were wrong!
If you make a mistake at one step, all the steps will go wrong, and all the subsequent formulas will go further and further away because of this initial step.
Woohoo, why does she always make such stupid mistakes?!
So embarrassing!
Ye Linlang complained to herself inwardly, feeling somewhat disappointed with herself, but she still put on a brave face in front of Jiang Qiran.
"I... I was just careless. I won't do it again."
Jiang Qiran narrowed his eyes slightly, he suddenly moved closer and hit Ye Linlang hard on the head!
"It hurts—I told you I'd become stupid if I did this!"
Jiang Qiran's handsome face was cold.
"If I don't hit you a few times, you might make the same mistake again. How dare you use carelessness as an excuse?"
"If you become an accountant in the future, and you make a mistake of a plus or minus sign or a decimal point, do you know that it would mean a loss of hundreds of thousands of dollars for the company?"
Ye Linlang pouted and touched her head with tears in her eyes.
“I’m not going to be an accountant…”
Seeing that Jiang Qiran still wanted to criticize her, Ye Linlang hurriedly continued to cover his mouth.
"Not only accounting, I won't be a math teacher, a cashier, a scientist or an experimentalist, or anything like that in the future!"
Jiang Qiran's face darkened when he heard this.
"Do you think that others would dare to hire you if you are so careless?"
Ye Linlang was originally speaking very proudly and was about to list all the professions related to mathematics, but who would have thought that Jiang Qiran's counterattack would be so powerful!
It was a fatal blow!
Ye Linlang was helpless.
"Okay, okay. They look down on me and I look down on them. It's okay if we just dislike each other, right?"
Jiang Qiran no longer wanted to pay attention to Ye Linlang, who was such a middle school student.
He directly snatched the cake from Ye Linlang's hand.
"Hey, hey, hey, do you know that it's immoral to steal other people's food? This is given to me by Miaomiao!"
Jiang Qiran simply ignored Ye Linlang, who was looking angry, and put the half-eaten cake aside, and took out a math book from Ye Linlang's schoolbag.
With a snap, Jiang Qiran placed the math book in front of Ye Linlang.
"Unit 3, page 221. Start memorizing the mathematical formulas for trigonometric functions now. I'll check in three minutes!"
Wait, why does Jiang Qiran remember it so clearly? Where are those formulas
Ye Linlang turned to page 221 in disbelief, and sure enough, it was full of knowledge and formulas about trigonometric functions!
"Can it be extended to five minutes?"
Ye Linlang asked weakly.
The young man's face was cold and handsome.
"You only have three minutes, or you won't be able to eat your cake or sushi."
