However, when he knocked for a long time, and finally the answer on the abacus in his hand was the same as the answer that Qian Duoduo spit out, the shopkeeper was shocked.

He raised his head and stared at Qian Duoduo in surprise: "Young Madam, this...?"

"What's the matter?" Qian Duoduo chewed melon seeds and looked out the window: "Shopkeeper, you should hurry up and report it. With your speed, when will you finish the calculation?"

The shopkeeper suddenly came back to his senses, and wiped the cold sweat on his forehead: "Oh... oh, report it now, report it now!"

After speaking, he picked up the account and quickly reported the next data.

Qian Duoduo thought about it for a while, dipped his fingers in the tea and kept drawing on the table for a while, and immediately came up with an answer.

Although the shopkeeper had some doubts about the data she gave, he didn't dare to veto it in person. He just wrote her data on another piece of paper, and then reported the next data, while his hand was moving the abacus. Follow the previous data.

After he finished the calculations, he was shocked to find that the three figures calculated by Qian Duoduo were completely correct, and...they did the calculations without even having an abacus. This...is really amazing.

Thinking of this, the shopkeeper raised his head: "Young Madam, what kind of algorithm is this? You don't even need an abacus?"

Qian Duoduo shook his head and shook his head: "Well, your young lady is very smart, I don't need an abacus, I just calculated it with my heart!" Qian Duoduo said triumphantly and looked at the shopkeeper: "Next!"

"Oh... oh..." The shopkeeper hurriedly looked at the fourth one and reported it.

Qian Duoduo frowned, "Didn't you forget this just now?"

"Ah? Is it over? The shopkeeper was stunned. Isn't this too fast?"

"It's already out!" Qian Duoduo frowned: "I've been waiting for you for a long time, what speed, can you hurry up?"

The shopkeeper hurriedly nodded: "Okay..." He looked at Qian Duoduo as he spoke, "That question just now?"

Qian Duoduo frowned: "Four thousand 850 three taels 45 Wen!"

"Oh..." The shopkeeper quickly bowed 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, and when she finished the accounting, he finally found that the young lady had been drawing on the table with her fingers dipped in tea while she was doing the accounting.

After thinking for a while, he finally walked up to Qian Duoduo curiously, looked at the desktop in front of her, and was shocked: "Young Madam, this...you calculated it by relying on these ghostly symbols?"

Qian Duoduo paused for a moment while eating the melon seeds: "These are drawn by me, how can they be called ghostly symbols?"

"Oh... oh..." The shopkeeper blushed in embarrassment and asked shamelessly, "Then what are these...?"

"This? This is the Shenzhou algorithm... Oh, you don't understand anyway, let's get rid of that pile of books first!" Qian Duoduo said impatiently and shook his hand.

"Oh..." The shopkeeper nodded, and when he turned around, he said unwillingly: "Then... Young Madam, we're done with the calculations, can you tell me about this Shenzhou algorithm...?"

Qian Duoduo frowned, always feeling that this matter was a bit troublesome, but seeing the shopkeeper's pleading eyes, Qian Duoduo finally nodded helplessly: "Okay, I'll teach you when I have time!"

"Really?" The shopkeeper said with a smile on his face.
