The Art of Problem Solving AOPS Volume 2 : and Beyond By Richard Rusczyk Sandor Lehoczky 7 the edition

Welcome to the Land of “ Obsession “ or rather “

Addiction “ for Maths, and many other things !

Some points to ponder ...

Are rich people good in Maths ? Do rich people care about Maths ? The girls above are surely rich ! ( how ? ) Are they very good in Maths ? In Mathematics ... Reverse ( or simply opposite ) of a TRUE statement is NOT necessarily False We can realize that by asking the above questions in a reverse way !

Are people good in Maths rich ? If you thirstily or “ ad lib “ answered Yes to the above questions... you forgot about the Kings, Queens, Misbehaved Jobless morons known as Prince, and Princess, Millionaires, Billionaires, Dacoits, Cyprians etc

Make a list of at-least 100 theorems named after rich kings, queens, Billionaire buffoons, heiress of Business mega-corporations or say Saudis.

( If you are not getting enough then you can include Lemmas ! ) :-D Do you know the life history of

Nikolai Ivanovich Lobachevsky, Abraham de Moivre, Niels Abel, Frank

Ramsey, Dmitri Egorov, etc Every student to learn the first

Axiom of Life ... “ if someone is too good in Mathematics, he will

be either poor, or will be dependent on meagre stipend or salary. “ [ Learn about graph of Rectangular Hyperbola xy = const say in x-axis you have skills in Maths and y-axis is your wealth ] There are Billionaires in this world just by selling lots of Pork ! Illegitimate; unwanted accident, of Millionaires; donates in 10,000$ suites per night. Saudi prince never counts cost of numerous “ girl friends “ [ Did not use other appropriate synonyms Trulls or Wenches ]

To lead a pauper’s life you do not have to solve some “ Unsolved problems since 300 years “, or say

3n + 1 problem etc.

You are in a danger zone ( with extremely high probability of being poor ) if you can solve the following problems itself ! { corollary – No rich person can solve these problems, do not even care ! } Question 1 ) If z1 and z2 are two complex numbers such that | z1 | = | z2 | + | z1 then Arg( z1 )

- z2 |

– Arg( z2 ) is _________ ?

Question 2 ) Is it TRUE or False that .... for all complex numbers z |z|

≤ | R(z) | + | Im(z) | ≤ √2 |z|

And z1 and z2 are two complex numbers with given c

> 0 then | z1 + z2 |2 ≤ ( 1 + c ) | z1 |2 + ( 1 +

)| z2 |2

Some Mathematics Teachers are “ so rich “ that they have cpu time of supercomputers for years to blow. Since last 64 years some jobless ones have been trying to find 33 to be written as sum of 3 cubes. So 33 = x3 + y3 + z3 where

Now Fallen Girls will have less money! ( Mathematicians? ) [ Should we even call them mathematicians ? ] found that patterns in the last digit of the prime numbers. In the first billion primes, a 1 is followed by a 1 about 18% of the time, by a 3 or a 7 each 30% of the time, and by a 9 it is 22% of the time. What do you think Fashion Models are doing with these ?

The above pictures are of Mathematicians, and of those; who are very good in Maths. These photos were taken just after they were rejected by Cougars! They went to Floozy asking for free s€ж! To save their skin they cooked-up an Axiom – “ No one good in Mathematics or no intelligent person ever went to a Bawd ! “ Now how does anyone defines the words “Good “, “ Mathematician “, “ intelligent “, “ Courtesan “ etc ?

Why does Boys and Men do the same mistake what their Biological Father did ? Becoming poor by donating to treacherous women; desperately ensuring the paramour to become rich !! So intelligent boys and men, regardless being good in Mathematics or not; never wasted money on girls ... ?? Really ??? Women teach Girls, starting quite early; the most important Axiom of life !!! Axiom – “ Boys and Men are Fools! They eagerly spend and splurge money on girls and women! It is so easy for a woman to become rich “

AOPS Art of Problem Solving Volume 2 and Beyond Chapter 1 - 13 upto Page 158 part 1 of 2 parts 7 th edition Richard Rusczyk Sandor Lehoczky ISBN 9780977304585 How many Axioms and Theorems can we have ? How do you prove or verify Axioms ? What did Godel prove ? what are differences between Axioms and Theorems ? Did Cohen mean that “ we can state any axiom and logically, step by step; prove whatever contradictory results we wish “ ?

We are in a world where “ her highness “ if states something it becomes an axiom “ proved “. Girls and women know how to attract, ..... money ....... We also stay in a world ... in which ... “ whatever you say, you think correct, or you do, or state; is TRUE and CORRECT! While what others are thinking, doing or stating may not ( most probably ) be correct !” In simple words “ Others are generally wrong! “ How does it matter how Gottlob Frege spoke English, Latin, or Logic ? Now disprove the Axiom – “ Boys and Men work hard to earn money, want to become rich; to easily donate to women ! “

Go ahead with your irrational addictions and obsessions ....
