However, when he knocked for a long time and finally the answer on the abacus in his hand was the same as the answer spit out from Qian Duoduo's mouth, the shopkeeper was shocked.
He raised his head and stared at Qian Duoduo in surprise: "Young madam, this...?"
"What's wrong?" Qian Duoduo chewed melon seeds in his mouth and looked out the window: "Shopkeeper, you should hurry up and report. At your speed, when can you finish the calculation?"
The shopkeeper suddenly came to his senses and wiped the cold sweat from his forehead: "Oh...oh, I'll retaliate, I'll retaliate!"
After speaking, he picked up the account and quickly reported the next data.
Qian Duoduo thought for a moment, dipped his fingers in tea and drew on the table for a while, and immediately came up with an answer.
Although the shopkeeper had slight doubts about the data she told, he did not dare to veto it face to face. He just wrote her data on another piece of paper, and then reported the next data, while his own hands were moving the abacus.
to the previous data.
After he finished the calculation, he was shocked to find that the three figures calculated by Qian Duoduo were completely correct, and... he calculated it without even an abacus. This... is really amazing.
Thinking like this, the shopkeeper raised his head and said, "Madam, what kind of algorithm are you doing? You don't even use an abacus?"
Qian Duoduo shook his head: "Well, your young lady, I am so smart that I can calculate it with my heart without using an abacus!" Qian Duoduo said proudly and looked at the shopkeeper: "Next one!"
"Oh...oh..." the shopkeeper hurriedly looked at the fourth one and reported out.
Qian Duoduo frowned: "Didn't I just forget about this?"
"Ah? Is it over? The shopkeeper was stunned. Isn't the speed too fast?"
"It's been out a long time ago!" Qian Duoduo frowned: "I've been waiting for you for a long time. What speed? Can you hurry up?"
The shopkeeper nodded quickly: "Okay..." Then he looked at Qian Duoduo: "What was the question just now?"
Qian Duoduo frowned: "Four thousand eight hundred and fifty-three taels and forty-five cents!"
"Oh..." The shopkeeper quickly lowered his head to record, and then quickly told Qian Duoduo the next one. Qian Duoduo drew the answer twice on the table with his fingers.
The shopkeeper stared blankly at her fingers. When she finished calculating the accounts, he finally discovered that the young lady had been drawing on the table with her fingers soaked in tea while she was doing the calculations.
After thinking about it, he finally walked up to Qian Duoduo curiously, looked at the table in front of her, and was shocked: "Young Madam, this... did you calculate it by relying on these ghost drawings?"
Qian Duoduo paused while eating melon seeds in his mouth: "I drew these, how can I say they are ghost drawings?"
"Oh...oh..." The shopkeeper blushed in embarrassment and asked shamelessly: "Then what...are these?"
"This? This is the Shenzhou algorithm... Oops, you can't understand it anyway. Let's get rid of those piles of ledgers first!" Qian Duoduo said and shook his hand impatiently.
"Oh..." The shopkeeper nodded, and when he turned around, he said reluctantly: "Then... Young Madam, we are done. Can you tell me about this Shenzhou algorithm...?"
Qian Duoduo frowned, always feeling that this matter was a bit troublesome, but looking at the shopkeeper's pleading eyes, Qian Duoduo finally nodded helplessly: "Okay, I will teach you when I have time!"
"Really?" The shopkeeper's face lit up and he said with a smile.
