"Ye Li, are you saying you know how to solve this problem?" Qin Jiale asked, her eyes filled with hope as she looked at Ye Li.
"Yes." Ye Li answered readily.
"Then can you tell me, how to solve this problem exactly? Why can't I get the solution I calculated." Qin Jiale shared her answer written on the draft paper with Ye Li.
"You got this part wrong. You should first solve this step, then the other one." Ye Li took the pen from Qin Jiale's hand and began to write on the paper.
