Magic math happens in our life. This conclusion was drawn based on my
study of some mathematical problems.
The first gain of some ability is to be able to resolve a very
annoying problem in a convenient way. In the moment I went into
bathroom this noon, an idea lightened my mind,
"Why don't I tell Jacques that he can assume that it is line segement
AB of Square ABCD to turn a 90 degree instead of the whole square?"
In this way, we can see that the line segment AB is turned to which
point. Based on the new position of AB, it is easy to decide where the
other three line segments would be placed. This actually is a problem
about the ability to think in a two-dimension plane.
The second gain of today's study is about probability, permutation,
and combination. A Baron GRE Test prepartion book gave a very clear
example of what is permutation. This helped me understand that every
(independent) thing can be substituted by a number in mathematics.
I would also recommend people who do not understand basic mathematical
ideas to review Baron GRE Test book for resolution. About 90 percent
of the math examples given in this book are clearly illustrated.
The third gain is to get to know why I was not good at resolving
problems about distance and numbers when I was in elementary school.
It is so easily illustrated in Baron's GRE Test preparation book. Of
course, most of all, I am a grown up now and these problems are no
longer problems to me anymore.
