After asking her question, she wrote and calculated on the paper for a long time, and finally threw down her pen, looking somewhat dejected.
"What's wrong?" Chen Ji leaned over and looked at the messy scribbles on the letter, and couldn't help but curl the corners of his lips.
Xu Ruantang looked utterly defeated. "I can't figure it out."
"Um?"
"I graduated from junior high school a long time ago. I was bad at math when I was in school. I want to calculate how much money I've earned, but I can't."
She hung her head in frustration, looking defeated.
Chen Ji was silent for a few seconds, then pulled up a stool and sat down next to her, his voice gentle: "I'll teach you."
Xu Ruantang lowered her eyelashes, a triumphant smile flashing across her eyes, but she quickly suppressed her happy smile and said, "Okay!"

"About one pound of flour, six ounces of milk, two eggs, a bowl of honey, a bowl of cooking oil, and a small handful of sesame seeds can make forty loaves of bread."
Xu Ruantang looked very serious.
Chen Ji recorded everything, his large, well-proportioned hands holding the pen, and lines of numbers quickly appeared on the letter paper.
"Your honey bread rolls cost about three cents each."
Chen Ji gave the answer in less than a minute.
Xu Ruantang's eyes were filled with shock as she looked at Chen Ji with admiration, exclaiming in an exaggerated tone, "Wow, you're so good at math! How did you do it? Can you teach me?"
