Mathematics
“Mathematics takes us still further
from what is human, into the region
of absolute necessity, to which not
only the world, but every possible
world, must conform.”
― Bertrand Russell

AMCs to AMO and IMO
The American Mathematics Competition Program
• The major mathematics competitions in the United States for Middle and
High School students
• Consists of
• American Mathematics Competition 8 (AMC 8)
• American Mathematics Competition 10 A and B (AMC 10)
• American Mathematics Competition 12 A and B (AMC 12)
• American Invitational Mathematics Examination I and II (AIME)
• USA Junior Math Olympiad (USAJMO)
• USA Math Olympiad (AMO)
• Success in the AMO leads to an invitation to Math Olympiad Summer
Program (MOSP) from which a team is chosen to represent the United
States at the very prestigious international competition, the International
Math Olympiad (IMO)

Competition Difficulty
Difficulty Over Time
• Math competitions have gotten much more difficult over time
• Resources are much better
• Students are much more competitive

Competition Difficulty
Difficulty Over Time
IMO 1959 #1
Prove that the fraction (21n+4) / (14n+3) is irreducible for every natural number n.
IMO 2010 #1
Determine all functions f:R → R such that the equality
f(g(x)y) = f(x)g(f(y)) holds for all real x and y where g is the floor function.
Competition winners are really “mini-professionals”
Extreme talent and hard work are required

Why Compete?
The Goals
Very few will actually achieve the top levels; so why compete?
• Hone problem solving skills that will serve one well beyond high school
• Be able to tackle problems that are difficult and time consuming
• Build confidence
• Strengthen quantitative skills
• Gain an appreciation for mathematics
• Help with college admissions??
• Best reason: Because the student wants to do more mathematics
page 23Version -eiπ
How to Prepare
American Education in Mathematics
• Lacking in many ways
• Insufficient progress in covering material
• Conditions students to think that all math problems should be doable
quickly
• Poor in developing mathematical thought
• Very little emphasis on proofs / mathematical writing
page 24Version -eiπ
How to Prepare
The Subject Matter
• Algebra
• Geometry
• Number Theory
• Discrete Math (Combinatorics / Graph Theory)
• Only the first two are covered in the standard high school curriculum
• But not to the required depth
• Maturity in the first two topics and in Number Theory and Discrete Math
will required outside work
page 25Version -eiπ
How to Prepare
Mathematical Writing / Proofs
• There are a number of students who do quite well on the AIME and qualify
for the USAMO, but don’t do well on the AMO
• One big cause is the inability to think and write mathematical arguments
(proofs)
• In some respects, this is the separation between those who can use
mathematics and those who can produce mathematics
• The ways to improve
• Start with basic proof techniques (induction, etc.)
• Read math proofs
• Do old contests that have proofs (ARML, HMMT, USAMO)
• Try the USA Math Talent Search

How to Prepare
The Secret …
• There is no secret; it’s just hard work
• Do LOTS and LOTS of problems that are uncomfortably difficult but not
impossible
• Don’t give up on problems too easily but don’t spend too much time on a
problem for the sake of efficiency

Questions?
FAQ
Q: Will a certain level of mathematics in the standard curriculum prepare a
student adequately for competition math? Precalc? AP Calc BC?
A: No, the material covered in those courses do not train a student because
• Much of the material in competition math is not in the standard
curriculum
• The material is covered in a shallow manner
• Students are not trained to struggle over problems
Q: How well would a student need to do to get into Harvard, Princeton, Yale,
etc.?
A: There is no guarantee to get into those institutions. Their admission criteria
are opaque; extremely strong students are often rejected and very weak one
students can be admitted.
page 29Version -eiπ
Questions?
FAQ
Q: When should a student start taking math contests?
A: Ideally, as soon as the student wants to. While the student’s school may not
offer a contest, there are other venues that can be found with some
investigation.
