After wearing the book, I was spoiled by the Prince Regent!

Chapter 214 The expression is getting out of control...

Xia Xinxin took a pen and wrote down the solution:
Let the number of pears be X and the number of fruits be Y.

The price of each pear is 11/9 coins, and the price of each fruit is 4/7 coins.

Then the binary equation can be listed:
11/9X+4/7Y=999
X + Y = 1000
The final solution is:

X=657 (units) Y=343 (units)

The total price of pears is 11/9×657=803 (text)

The total price of fruit is 4/7×343=197 (text)

The second question:

The number of chickens and rabbits in the same cage is unknown, and 36 heads are exposed in the cage.

Count fifty pairs of feet, how many chickens and rabbits are there?
A well-known arithmetic problem in ancient times, chickens and ducks in the same cage.

Xia Xinxin reasoned like this, and wrote out the solution as soon as she was done.

Followed by the third question:

A group of dolls sit around the table and divide the fruit. Each person has 6 and 6 is left, and each person has 7 and 7 is less. Smart friends do the math, how many dolls are there?
It's hard to calculate hard, but in algebra, these questions are simply pediatrics. Xia Xinxin glanced at them and wrote them out without even thinking about them.

Question after question...

She is like a problem-solving machine.

At first, everyone couldn't understand what she wrote, but after reading it for a while, they understood!
After all, it is still possible to do this!
This kind of substitution algorithm is simpler and easier to understand than the deduction method mentioned by Master Su!

The pupils of all the Confucian scholars who were small and big were shocked, and their rigid brains were almost exploded like an atomic bomb!
The room was full of elegant birds, all of them stared with huge eyes and opened their mouths, watching Xia Xinxin solve the problem in a daze!

Su Changlin stood aside and was also shocked.

He studies arithmetic and has read many ancient books on arithmetic deduction from all over the world, but he has never seen this kind of substitution algorithm. How could Miss Xia...

She made it herself?

He was shocked, pleasantly surprised, and looked at her with extremely complicated eyes.

Su Wan'er sneered all over her face, gloating and waiting for Xia Xinxin to show her stupidity, and then obediently eat shit!
However, after Xia Xinxin solved the above questions one by one, this kind of gloating smile gradually became stiff, distorted, unbelievable, and her expression gradually became out of control...

No, it's not possible...

How can this little hoof who can't read big characters know everything?

Also, it's all right!

She couldn't understand what she wrote, but the conclusions drawn by her superiors were all correct!
She had already asked her brother for the solution and the answer in advance, and waited to show it off later, so she knew the answer.

She stared at the twisted eyes, trying to examine the wrong answers, but no, every one was right!
how so! !

Her pupils trembled, she stared at Xia Xinxin firmly, and couldn't help shaking her eyes.

A few great Confucian scholars from the Hanlin Academy also sat in the back and listened to the lectures. They originally wanted to listen to Su Taifu's lectures to see his level. After all, he was too young to be His Majesty's Taifu.

Unexpectedly, I found a treasure girl!
This little girl's substitution algorithm is really wonderful, easy to understand, easy to learn, this is to revolutionize the entire history of arithmetic in the Great Yan Dynasty!
Fang Daru, a great Confucian of a generation, stared excitedly at Xia Xinxin's non-stop solving problems, like an eagle seeing a chicken, or a beast seeing its prey. The regent has forgotten such a big thing.

It was his assistant who quietly came in to remind him that the prince was waiting in the Hanlin Academy.

Only then did Fang Daru remember that the prince wanted to meet with him today to discuss the matter, so he hurriedly got up and left Chongguang Hall with three steps.

Back at the Hanlin Academy, the prince was already waiting there.
