Biquge lightnovelpub.net, the latest update of the blackest male master always wants to set my latest chapter!

Because the college entrance examination mathematics is to take these eight books.

For this reason, in the past few days after Su Yan had attached to this body, he basically completed the eight compulsory plus the five years of college entrance examination questions.

She took the paper just made by Ji Xingyu and read it again.

Then

"With regard to the knowledge points of sufficient and necessary conditions, the judgment of true propositions, inverse propositions, and function analysis, these knowledge points go back to reading books by themselves."

Ji Xingyu looked at Su Yan with a strange look

"Teacher, don't you teach me?"

Su Yan paused, and then thought about it

"These points ~ lightnovelpub.net ~ will understand, no need to teach."

She said very seriously and was not joking at all.

Ji Xingyu thought that he might have found a fake teacher.

Then, he pointed his finger at the last big question.

"This question?"

Su Yan bowed his head and looked for a while.

"Sum of Sequences, Using Split-Term Cancellation"

Ji Xingyu waited for Su Yan's next paragraph, but found that Su Yan did not continue to say anything.

He asked

"Then?"

"Done again, you can get the result, the result is -2n \\ n + 1"

Ji Xingyu listened to Su Yan's concise words.

He was silent.

Su Yan looked at him in confusion, half a ring

"Do you remember the expressions that cancel the split term? The formula is a bit long. You can read about it on page 83 for a description.

Ji Xingyu didn't speak.

Because Yan Yan Suyan looked at him, he seemed to be saying, ‘I ’ve said it very well, it ’s understood by individuals. ’

Ji Xingyu opened the book in his hand, holding a pen in one hand, writing words in the blank of the paper, and rustling.

After Su Yan talked to Ji Xingyu, he turned his head to Ji Yan's eyes.

She froze for a moment.

Then he pushed the dried fruit around him to him.

Ji Yan looked at the snack that was pushed in front of her.

Did not move.

"dislike?"

Su Yan asked loudly.

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

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

Ji Yan looked at the raisins, then bowed her head and ate it in silence.

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

ten minutes later.

Su Yan's eyes moved away from the ipad.

Looking at Ji Yan, he found those raisins motionless.

Su Yan reached out, peeled a few pistachios, and passed them.

He bowed his head and ate it very obediently.

Wait until she feeds several times, and as long as she feeds, he eats.

Therefore, Su Yan was feeding while watching the live broadcast.

Just like owning a pet.

Fortunately, Ji Yan is very supportive.

Another half hour passed.

Ji Yan swallowed the pine nut in his mouth, and when Su Yan fed again, he finally spoke.

"Do you like watching this?"

Then he finished talking and swallowed the peanuts handed over by Su Yan silently.

"still alright"

She answered.

Mindful of flowers remind

"Host, you should broadcast live."

As a system, its responsibilities, in addition to sending tasks to the host and guiding the completion of tasks, can also be used as an alarm clock.

Su Yan looked at the time, and then

"Well, today's tuition is over."

Ji Xingyu's pen meal.

Stopped writing.

Now that tuition is over, there is no reason why Suyan should stay here.

Just when I was leaving, I didn't say a word while watching Ji Yan, but sat on the chair and watched her every move.
