From Su Mucheng's reaction, Qiao Ze suddenly realized something.
After pondering for a moment, he quickly wrote an equation on the paper and asked, "When you see this equation, can you imagine its geometric figure?"
Su Mucheng nodded and said, "Two intersecting lines, right?"
Qiao Ze nodded, then wrote another set of equations on the draft paper.
Su Mucheng still answered instantly, "This is a symmetrical wave pattern."
For the third one, Su Mucheng thought for about ten seconds, "Two irregular surfaces intersecting at point X."
Qiao Ze nodded again.
But with the fourth one, Su Mucheng thought for five minutes and only concluded that it represented two hexahedra with Qiao Ze's hint.
The fifth, the sixth... left Su Mucheng completely baffled.
She could only use her soft, endearing big eyes to look pitifully at Qiao Ze, while pouting her lips.
Well, if intelligence isn't enough, cuteness will do the trick.
