Because the mathematics of the college entrance examination is to test these eight books.
For this reason, in the past few days after Su Yan possessed this body, he basically finished reading the eight compulsory books plus the actual exam papers for the previous five years.
She took the test paper that Ji Xingyu made just now, and read it again.
Then, said
"About the knowledge points of sufficient and necessary conditions, true propositions, judgments of inverse propositions, and function analysis, these knowledge points go back and read books by yourself."
Ji Xingyu looked at Su Yan with a strange expression
"Teacher, don't you teach me?"
Su Yan paused, then thought about it carefully
"These points can be understood by reading a book, and there is no need to teach them."
She said it very seriously, not joking at all.
Ji Xingyu felt that...he might have found a fake teacher.
Then, he pointed to the last big question.
"This question?"
Su Yan lowered her head and looked at it for a while.
"Summation of a series of numbers, using the split term cancellation method"
Ji Xingyu waited for Su Yan's next words, but found that Su Yan had no intention of continuing.
he asked
"And after that?"
"Do it once, you can get the result, the result is -2n\n+1"
Ji Xingyu listened to Su Yan's concise words.
He fell silent.
Su Yan looked at him suspiciously,
"Do you remember the expression of split term cancellation? The expression is a bit long, you can read page 83 of the book for related explanations."
Ji Xingyu didn't open his mouth to speak.
Because Su Yan looked at him, it seemed to be saying, 'I've made it very clear, everyone can understand it. '
Ji Xingyu opened the book in his hand, held a pen in one hand, and wrote in the blank space of the paper, making a rustling sound.
After Su Yan finished speaking with Ji Xingyu, she turned her head to meet Ji Yan's eyes.
She froze for a moment.
Then he pushed the dried fruit beside him to him.
Ji Yan looked at the snacks that were pushed in front of him.
didn't move.
"do not like?"
Su Yan asked aloud.
Ji Yan's mouth moved, but he didn't speak for a long time.
She thought for a while, stretched out her hand, and tried to put a few raisins to his lips.
Ji Yan looked at the raisin, then lowered his head and ate it silently.
Seeing him eating, Su Yan pushed all the raisins beside her to him.
ten minutes later.
Su Yan looked away from the top of the ipad.
Looking at Ji Yan, he found that the raisins had not moved.
Su Yan reached out, peeled a few pistachios, and handed them over.
He lowered his head and ate obediently.
After she fed it a few times, he found that as long as she fed it, he would eat it.
So, Su Yan fed while watching the live broadcast.
It's like having a pet.
But fortunately, Ji Yan is easy to raise, and he will not refuse anyone who comes to him.
Another half hour passed.
Ji Yan swallowed the pine nuts in his mouth, and when Su Yan fed them again, he finally spoke.
"You enjoyed watching this?"
After finishing speaking, she silently swallowed the peanuts that Su Yan handed over.
"Well enough"
she answered.
In my mind, Xiao Hua reminded
"Host, it's time for you to broadcast live."
As a system, its responsibilities include not only sending tasks to the host and guiding them to complete them, but also functioning as an alarm clock.
Su Yan checked the time, then said to Ji Xingyu
"Okay, today's tutoring is over."
Ji Xingyu's pen paused.
He stopped writing.
Now that the tuition is over, Su Yan naturally has no reason to stay here.
It's just that when he was about to leave, Ji Yan didn't say a word, but sat on the chair and watched her every move.
