I went to see my Academic Supervisor today.
He asked me what is Critical Thinking?
I answered him with my own version of answer.
He then gave me this mathematical question. How much is 99 x 5?
I answer 495. He asked me, how did I get the answer. I answer. I times the equation one by one. 9 x 5, 45 balance 4 bring it up on 9. and 9 x 5, 45 plus 4, 49. ( this was what I learnt in school). so in the end I got 495.
He said, that is the normal way of doing things. That is not critical thinking.
I paused...Are there any other ways to get the answer....
I cannot answer him.
He then said why I don't give you 82, 53, 37...Why did I used 99...
Again I paused I can't answer him...
I went back. Google the meaning of critical thinking. Google for different ways to get the answer of 99 x 5...but I still cannot get why he use 99 instead of other number?
I start to think. maybe if I was alert enough I would have used 500 - 5. Since 100 x 5 = 500. 99 x 5 = 500 - 5 = 495.
Is this the answer that my academic supervisor was looking for?
Does critical thinking means finding other ways, approach of doing something?
Any body has a clue?
