12+15(3+1)/6=?
I should know this, right?
Huff! Huff!
Lin Baici's breaths became heavier and heavier; the more he tried to quickly solve the problem, the more his mind turned into chaos. This state was like a heavy stone, weighing a thousand pounds, pressing on him, causing cold sweat to start beading on his forehead.
Lin Baici felt as if he had returned to the high-stakes college entrance examination hall, working on the final math question. The problem was difficult, and there wasn't much time.
If he gave up, he would lose more than ten points, but attempting it didn't guarantee success either. Perhaps it would be better to use the remaining time to check the other questions.
Huff! Huff!
Lin Baici felt an unbearable pressure in his chest, and couldn't help but pound it a few times.
Bang! Bang!
The characters on the paper seemed to twist, forming a vortex that could swallow both one's vision and soul.
