"This way, you calculate 10 items at a time, and write the total next to it. This way, even if you make a mistake in the middle, you don't have to recalculate everything. After you've calculated all the items, you can add all the totals together to know the final price."
"That's right! How come I didn't think of that?"
Huang Jiajia thought the little girl in front of her was really smart, and immediately started calculating as she had said.
This time she quickly calculated the result, and it was the same as Qiao Qiqi's result: 51 yuan and 36 fen.
Huang Jiajia was so excited she almost cried. Thinking that this was all the good idea of the girl in front of her, she immediately looked up at her and said, "You are really good at using an abacus! Can you teach me? If you are willing to teach me, I will give you 50 yuan for these things."

Upon hearing this, Qiao Qiqi immediately recalled the time when the original owner of the body and Hou Yan went shopping in town a while ago.
The supply and marketing cooperative did come at that time.
Seeing Qin Huai carrying his things out, Qiao Qiqi quickly laughed it off and said, "You might be mistaken. I haven't been to town in a long time, and I have a very ordinary face."
