"Hmm~, we also need some symbols or something!"

Liu Hong bit the end of his pen, frowning as he looked at the two pages of paper.

Liu Hong then found a copy of "Nine Chapters on the Mathematical Art" and copied out some of the symbols and formulas from it. He then added in the basic mathematical formulas from later generations that he could recall.

This includes basic calculation methods, measurement methods, area and volume calculations, and so on.

It took about an hour to finally finish.

"Hmm, there seem to be a few things wrong with this function?"

Looking at the several advanced function formulas recorded on the last page of the paper on the desk, Liu Hong scratched the back of his head, feeling a bit of a headache.

When it comes to learning a subject, other things are fine; even if you can't remember everything clearly, it's not a problem to remember the general outline.

But math is an exception. If you make even the slightest mistake or your memory is even slightly hazy, you'll still get it wrong no matter how hard you try.

Mathematics is indeed difficult!

There's a saying, isn't there?

If a student is studying something else, you should push him a little, and he might make some progress.

But with math, even if you beat him to death, he still won't understand!

Liu Hong clearly belongs to the latter category. It's already quite good that he can remember the basic things he learned in elementary school.

"Ugh, damn it... I'm the emperor now, and I still have to deal with these damn things. It's such a headache!"

Looking at the few vague formulas he had finally come up with, Liu Hong sighed and couldn't help but mutter a curse under his breath.

I couldn't help but recall the painful experience of being tormented by math when I was in junior and senior high school.

"Forget it, there are so many smart people in the Han Dynasty, let's just make things difficult for them!"

Liu Hong sighed softly, then crumpled the last page of the paper about functions into a ball and tossed it aside.

"Someone come here!"

"exist!!"

Two Imperial Guardsmen standing at the entrance of the hall quickly entered the hall and bowed to Liu Hong.

"What are your orders, Your Majesty?"

"Summon Minister of Works Yuan Feng, Zhang Zhen, and all the doctoral students from the Engineering College to an audience!"

"promise!!"

The two guards accepted the order and quickly left.
