Lu Xiaobu glanced at the problem and felt a headache coming on.
Actually, it's not that he couldn't solve it, it's just that he had genuinely forgotten some of the formulas and such.
If he had just graduated from high school a few years ago, he might still remember some of it. But he had come from Earth, and it was unknown how long it had been since he graduated, not to mention he had been on Water Blue Star for several years.
He really couldn't remember those formulas.
The people around were also discussing.
"Do you guys think Young Master Lu can solve it?!"
"Who knows! I just calculated 6, and the stall owner said I was wrong!"
"I got 12, and the stall owner said I was wrong too!"
"Could it be that this problem doesn't have a correct answer at all?!"
"Probably not, he wouldn't go that far. This problem is probably designed with many traps!"
"Let's see if Young Master Lu can solve it!"
"..."
At that moment, Xiao Zhi suddenly spoke up: "The answer is 7.5."
