Nino's tone was a little sarcasm.

really.

Although because of Su Yang's cooking, she didn't dislike him that much.

just.

Sure enough, it's still annoying.

Nino hates others to join her sister casually, and hates that others look down on her sister.

and.

She doesn't think her grades in elementary school are that bad.

"I also passed a 100 mark in elementary school!" Nina said.

"If you don't believe me, I can show you my paper."

"I kept it well."

...

"Oh?" Su Yang looked at her, "So what grade is it?"

"Probably... the third grade." Nina's eyes deflected. "Well, it's probably the second grade!"

So what happened to the third grade?

Was there a waterfall in the third grade?

"You all sit down for me!"

Su Yang put the teaching materials on the table and asked their five sisters to sit on the table.

"Don't think that your level is greatly underestimated by me."

"For example, who remembers this two-dimensional linear equation?"

"...Isn't this very simple?" Yihua moved her short hair lightly, "What's the problem of a chicken and a rabbit in the same cage."

"Yes." May also said. "I still remember the Pythagorean theorem."

"Very good." Su Yang nodded.

"Then you beat me now," he said. "Give me 100 points on the subject of elementary school."

"Yutaba!"

"Ah...Yes!" Yotsuba stood up immediately after being called.

"Go and get the copier out." Su Yang said.

"Okay! Obtained!"

Yotsuba immediately assisted in the work.

In the end, five papers appeared in front of the quintuplets.

Su Yang uses math papers.

There are only 20 calculators and 3 word problems.

"It's a pediatrics." Looking at the topic, May, she thinks she can do it.

Su Yang is too much.

What 12X13. What 22X88, what 95X104...

She raised her hand.

"Can I use a calculator?"

"No," Su Yang said. "Have you ever seen us use calculators in school?"

"what……"

May felt the malice of the world.

"Either mental arithmetic or written test!" Su Yang said.

Sanjiu's gaze fell on the subject, looked at it, and then raised his head. "Don't let me use the calculator, then, Teacher Su Yang, can you completely get rid of the calculator?"

"For example, do you know what **7X**0 is equal to?"

"If you can answer, then I don't need it."

...

Su Yang glanced at her.

Without even thinking about it, he said casually, "***"

But May curiously took out the phone and called up the calculator.

The input was made.

"Exceeded, exceeded the standard—"

The calculator didn't respond for a long time, and it took about twenty seconds before the numbers appeared.

It was exactly the same as Su Yang's mental arithmetic.

"Amazing--"

Watching this situation, the sisters are not surprised.

Then he looked at his topic convincingly.

Um.

95X104 and the like don't seem to be so difficult to accept.

"It's not allowed to whisper," Su Yang said.
