Bab 292: Disappointment

"That's 8 strings and 960 copper coins. I'm just forty copper coins short to make it 9 strings."

"Mother, I've calculated it. Do you think it's right?" Chu Jin stood up happily with both hands on the table and ran two laps on the spot. He was extremely happy. He had been learning abacus for some time now.

It was just that he had made mistakes before.

This time, he was very confident.

"That's right." Ye Muyu nodded.

She was very satisfied with her son's abacus calculation, but she was not satisfied with this child. He was not even six years old, but he had the through of spending 9 strings of copper coins without blinking.

"However…" Chu Jin stopped and looked at Ye Muyu in confusion.

"Lil' Jin, I'm afraid you don't have nine pennies."

Chu Jin, "Mother, I have it. I've calculated it. Uncle Chu Xing also told me that it would be more than ten strings of copper coins. At least fifteen hanging coins will be given to me."
