how many years have passed after I had calculated the fraction division. Few seconds later I rembered how to do it .
But I had completely forgot to resolve quadratic formula. I wonder, in which field of my daily life
those calculation was effectively valuable.
Anyhow only one definate answer in math was so refreshing. In my brain fresh air peneterated at seconds, is this exaggeration ?
It must be one of enjoyable training in future life for some people.
I am writing remebering the news that in Thailand the number of the aged one-person living is extremely increasing,
and those women go to school . Their uniform is cute, unrare from daily life and they seemed to enjoy to meet togather .
