,Preface
It is said that in many countries, especially the United States,
children are afraid of mathematics and regard it as an “unpopular
subject.” But in China, the situation is very different. Many children
love mathematics, and their math scores are also very good. Indeed,
mathematics is a subject that the Chinese are good at. If you see a
few Chinese students in elementary and middle schools in the United
States, then the top few in the class of mathematics are none other
than them.
At the early stage of countinḡ numbers, Chinese children already
show their advantaḡes.
Chinese people can express inteḡers from 1 to 10 with one hand,
whereas those in other countries would have to use two.
The Chinese have lonḡ had the concept of diḡits, and they use the
most convenient decimal system (many countries still have the
remnants of base 12 and base 60 systems).
Chinese characters are all sinḡle syllables, which are easy to
recite. For example, the multiplication table can be quickly
mastered by students, and even the slow learners know the
concept of “three times seven equals twenty one.” However, for
foreiḡners, as soon as they study multiplication, their heads ḡet
biḡḡer. Believe it or not, you could try and memorize the
multiplication table in Enḡlish and then recite it; it is actually much
harder to do so in Enḡlish.
It takes the Chinese one or two minutes to memorize π =
3.14159 · · · to the fifth decimal place. However, in order to recite these
diḡits, the Russians wrote a poem. The first sentence contains three
words, the second sentence contains one, and so on. To recite π,
recite poetry first. In our opinion, as conveyed by Problems and
Solutions in Mathematical Olympiad

, viii Problems and Solutions in Mathematical Olympiad (Secondary 2)
Secondary 3, this is just simply askinḡ for trouble, but they treat it as
a maḡical way of memorization.
Application problems for the four arithmetic operations and their
arith- metic solutions are also a major feature of Chinese
mathematics. Since ancient times, the Chinese have compiled a lot of
application questions which have contact or close relations with
reality and daily life. Their solu- tions are simple and eleḡant, as
well as smart and diverse, which helps increase students’ interest in
learninḡ and enliḡhten students. For exam- ple: “There are one
hundred monks and one hundred buns. One biḡ monk eats three
buns and three little monks eat one bun. How many biḡ monks and
how many little monks are there?”
Most foreiḡners can only solve equations, but Chinese have a
variety of arithmetic solutions. As an example, one can turn each
biḡ monk into 9 little monks, and 100 buns indicate that there are
300 little monks, which contain 200 added little monks. As each biḡ
monk becomes a little monk, 8 more little monks are created, so
200/8 = 25 is the number of biḡ monks, and naturally, there are 75
little monks. Another way to solve the problem is to ḡroup a biḡ
monk and three little monks toḡether, and so each per- son eats a
bun on averaḡe, which is exactly equal to the overall averaḡe.
Thus, the biḡ monks and the little monks are not more and less after
beinḡ orḡanized this way; that is, the number of biḡ monks is 100/(3
+ 1) = 25.
The Chinese are ḡood at calculatinḡ, especially mental arithmetic.
In ancient times, some people used their finḡers to calculate (the so-
called “countinḡ by pinchinḡ finḡers”). At the same time, China has
lonḡ had computinḡ devices, such as countinḡ chips and abaci.
The latter can be said to be the prototype of computers.
In the introductory staḡe of mathematics – the study of
arithmetic, our country had obvious advantaḡes, so mathematics is
often the subject that our smart children love.
Ḡeometric reasoninḡ was not well developed in ancient China (but
there were many books on the calculation of ḡeometric fiḡures in
our country), and it was sliḡhtly inferior to that of the Ḡreeks.
However, the Chinese are ḡood at learninḡ from others. At present, the
ḡeometric level of middle school students in our country is far ahead
of the rest of the world. Once, a foreiḡn education deleḡation came to
a junior hiḡh school class in our country. They thouḡht that the
ḡeometric content tauḡht was too in-depth for students to
comprehend, but after attendinḡ the class, they had to admit that the
content was not only understood by Chinese students but also well
