Chapter 71: Plunge Pool

"Keep your voices down. She'll be so smug if she hears you."

In the room, Lin Xiaoyue had already heard it.

She felt good.

But what was she at this time?

She was preparing the teaching materials for Liang Chengcai tomorrow.

What was the content?

It was the Arabic numerals and the explanation of the decimal digits.

That's right, one had to learn Arabic numerals before learning arithmetic. This was the most basic knowledge.

In addition to preparing materials for Liang Chengcai, Lin Xiaoyue also prepared a copy for Lin Xiaozhi so that he could practice it.

Her brother was surprisingly serious when it came to learning, which made Lin Xiaoyue sigh in her heart. If her brother were born before the end of the 21st century, he would definitely be a straight-A student.

This made Lin Xiaoyue even more determined to send her little brother to school.
