"Mathematics textbook?"

Ying Zheng was stunned when he heard this and asked tentatively, "There seems to be something about the calculation in this next village, which one can be used?"

"It's a bit difficult to use until now, but it's not very useful..."

After hearing this, Zhao Long said, "Let's teach them basic addition, subtraction, multiplication and division first?"

Addition, subtraction, multiplication and division?

Ying Zheng was stunned when he heard this, and then smiled, "I'm afraid this gentleman wants to do it himself..."

"Hey, it's very simple!"

Zhao Long smiled and said, "First teach them Arabic numerals, then calculate symbols, and finally teach them how to calculate. In fact, I will tell you about these things to Lao Si and Lao Feng, and they should be able to understand them easily...

…”

“That’s true…”

Ying Zheng nodded after hearing this, "Then follow what the sir said!"

Several prisoners walked in and opened a prison door, "Cheng Miao?"

"It's a criminal..."

In the cell, Cheng Miao was studying and thinking deeply at a word on the wall. When he heard him call him, he quickly turned around, "I don't know what instructions do you have?"

"Tell your Majesty the order to see him!"

What?

His Majesty?

After hearing these words from the prison guards, Cheng Miao was shocked and surprised.

Then, I couldn't help but feel excited and burst into tears.
