Hua Jinyan's gaze fell on the problem as Ma Ming pointed at the question on the whiteboard with his hand moving down until it paused on the watch on Ma Ming's wrist.
The answer was on the verge of revealing itself.
Hua Jinyan's eyes briefly sparkled before he quickly lowered his eyelids.
Ma Ming asked again, "Can't think of the answer?"
"Can't think of it."
Little Taotie tilted his head, his tiny brows knotted, and his large eyes were fixed on the problem as if staring hard enough could produce the answer.
Ma Ming looked toward Hua Jinyan, who appeared to be deep in thought with his eyes cast down, and decided not to trouble the two children further. He turned to Tao Shen and Tao Bin and asked, "Do you have the answer?"
Tao Bin was quite frank, shaking his head: "No."
Tao Shen kept his head down, not daring to meet Ma Ming's penetrating gaze.
"Dot." He said the answer softly.
Tao Bin was surprised: "How can it be a dot? Impossible, let me try!"
