As Kate walked towards the podium, she took the chalk from the math teacher's hand and then stood in front of the black board.
Without even hesitating for a second, she took the eraser from the box, erased the wrong problem, and then changed it.
Finally changing the problem and the answers, she looked at the board once again, confirming that there was nothing wrong anymore. She then looked at the math teacher and said:
"The previous problem is unsolvable since the problem was incorrect; change the problem into the right one, and then it finally has the answer," Kate said in a cold tone as she slowly put the chalk down on the math teacher's hand.
Admiration and worship made their way into the math teacher's eyes as she looked at the problem on the board and then at the 'genius' student that was making her way towards her seat.
