Chapter 354

Because the entrance examination of mathematics is to test these eight books.

For this reason, in the days after su Yan attached himself to this body, he basically completed the eight required questions plus the real questions of the college entrance examination in the previous five years.

She took Ji Xingyu's test paper and looked it over again.

Then, Dao

"on the knowledge points of sufficient and necessary conditions, true proposition, judgment of converse proposition, function analysis, these knowledge points go back to read by themselves."

Ji Xingyu looked at Su Yan with a strange look

Su yandundun, and then carefully think about

"these points, reading can understand, do not need to teach."

What she said was very serious. She was not joking at all.

Ji Xingyu thinks that... He may have found a fake teacher.

Then he reached for the last big question.

"This question?"

Su Yan looked down for a while.

Ji Xingyu is waiting for the next part of Su Yan, but he finds that Su Yan didn't continue to talk about it.

He asked

"and then?"

"Once done, you can get the result. The result is - 2n \ n + 1"

Ji Xingyu listens to Su Yan's terse words.

He was silent.

Su Yan looked at him doubtfully, half ring

"do you remember the expression of split term elimination? It's a little long. You can read on page 83 and have relevant explanations. "

Ji Xingyu didn't speak to Zhang.

Because Su Yan looked at him as if he was saying, "I've understood what I've said. I can understand it all by myself."

Ji Xingyu opens the book in his hand, holds a pen in one hand, and writes in the blank of the paper, making a rustling sound.

After su Yan and Ji Xingyu have finished speaking, one side of the head is opposite to Ji Yan's eyes.

She froze for a moment.

Then push the dried fruit around him.

Ji Yan looks at the snack pushed in front of him.

No movement.

"Don't like it?"

Su Yan asked aloud.

Ji Yan's mouth moved, but he didn't speak.

She thought for a moment, reached out and tried to pass some raisins to his lips.

Ji Yan looks at the raisin, then lowers his head and eats it silently.

Seeing him eating, Su Yan pushed all the raisins around him to him.

Ten minutes later.

Suyan's eyes moved away from the top of the iPad.

Looking at Ji Yan, he found that he didn't move the raisins.

Su Yan reached out, peeled off some pistachios and handed them over.

He bowed his head and ate obediently.

When she feeds several times, he will eat as long as she feeds.

As a result, Su Yan watched the live broadcast while feeding.

It's like having a pet.

But fortunately, Ji Yan is very good to raise. He can eat whatever he wants.

Another half hour passed.

Ji Yan swallows the pine nuts in his mouth. When Su Yan feeds them again, he finally talks.

"Do you like it very much?"

Then finish saying, and silently swallow the peanuts from Su Yan.

"Yes"

she replied.

In mind, floret reminds

"host, it's time for you to live."

As a system, its function is not only to send tasks to the host, but also to guide the completion of tasks, and to act as an alarm clock.

Su Yan looks at the time, then tells Ji Xingyu, "OK, today's tutorial is over."

Ji Xingyu's pen.

Stop writing.

Since the tutorial is over, naturally Suyan has no reason to stay here.

Just to leave, looking at Ji Yan did not say a word, but sitting in the chair has been watching her every move.
