Because for the college entrance exam mathematics, these eight books are what they test.
For this reason, after Su Yan transferred into this body, she basically went through these eight required texts along with the past five years of real college entrance exam questions in a few days.
She took the test paper that Ji Xingyu had just completed and looked it over again.
Then, she said
"Regarding the knowledge point of sufficient and necessary conditions, judgent of true propositions and converse propositions, function analysis, look up these few points in the book by yourself."
Ji Xingyu looked at Su Yan with a strange expression
"Aren’t you going to teach ?"
Su Yan paused, then thought carefully
"These points can be understood by reading the book, no need for teaching."
She said this very seriously, not joking at all.
Ji Xingyu felt... he might have found a fake teacher.
Following, he pointed his finger at the last major question.
"This question?"
Su Yan looked down and stared for a while.
"Summation of sequences, use the thod of splitting and cancelling terms."
Ji Xingyu waited for Su Yan to continue, but found that Su Yan had no intention of continuing.
He asked
"What’s next?"
"Work through it once, and you’ll get the result, which is -2n\n 1."
Ji Xingyu listened to Su Yan’s concise words.
He fell silent.
Su Yan looked at him puzzledly for a while
"Can you rember the expression for splitting and cancelling terms? The expression is a bit long, you can look at page 83 in the book, it has related explanations."
Ji Xingyu did not open his mouth to speak.
From Su Yan’s gaze, it seed as if she was saying, ’I’ve made it very clear, anyone can understand.’
Ji Xingyu opened the book in his hands, held a pen in one hand, and wrote words on the blank part of the paper, making a rustling sound.
After Su Yan finished speaking with Ji Xingyu, she turned her head and her gaze t with Ji Yan’s.
She was stunned for a mont.
Then she pushed the dried fruits beside her towards him.
Ji Yan looked at the snacks that had been pushed in front of him.
He didn’t move.
"Don’t like them?"
Su Yan asked aloud.
Ji Yan moved his mouth, but didn’t speak for a while.
She thought for a while, then stretched out her hand, tentatively offering a few raisins to his lips.
Ji Yan looked at the raisins, then lowered his head, and quietly ate them.
Seeing that he was eating, Su Yan pushed all the raisins beside her towards him.
Ten minutes later.
Su Yan’s gaze moved away from the iPad.
Looking at Ji Yan, she noticed that he hadn’t touched the raisins.
Su Yan reached out, peeled a few pistachios, and handed them over.
He lowered his head, and obediently ate them.
After feeding him a few tis, she found that as long as she fed him, he would eat.
Hence, Su Yan watched the live broadcast and continued to feed him on the side.
It was as if she had raised a pet.
But fortunately, Ji Yan was easy to feed, accepting whatever was given without refusal.
Another half an hour passed.
Ji Yan swallowed the pine nuts in his mouth, and when Su Yan fed him again, he finally spoke.
"Do you really enjoy watching this?"
Then after saying this, he silently swallowed the peanuts Su Yan handed over.
"It’s okay"
She answered.
In her mind, Xiao Hua reminded
"Host, it’s ti for your live stream."
As a system, its duty, besides issuing tasks to the Host and guiding her in completing them, was also to function as an alarm clock.
Su Yan looked at the ti, then said to Ji Xingyu
"Alright, today’s tutoring session is over."
Ji Xingyu’s hand paused.
He stopped writing.
Since tutoring was over, naturally Su Yan had no reason to stay here any longer.
But as she was about to leave, she looked at Ji Yan, who didn’t say a word, but continued to sit in the chair, watching her every move.
